The document provides information on performing a precordial examination, including history, examination technique, inspection, palpation, and auscultation. It discusses examining the apical impulse in detail, including location, duration, size, force, and variations such as absence, tapping, hyperdynamic, and heaving. Characteristics and causes of a displaced or diffuse apical impulse are also covered.
This document discusses right bundle branch block (RBBB) in the electrocardiogram (ECG). It begins by explaining normal ventricular conduction, then describes RBBB. Key points of RBBB include a QRS duration of over 110ms, an rSR' pattern or notched R wave in lead V1, and a wide and slurred S wave in leads I and V6. The document contrasts RBBB and left bundle branch block (LBBB) and provides illustrations of complete RBBB, incomplete RBBB, intermittent RBBB, and RBBB with left anterior fascicular block. It emphasizes using lead V1 and the direction of the terminal QRS force (upward for RBBB, downward for LBBB)
Atrial fibrillation and atrial flutter are types of arrhythmia where the heart beats irregularly. Atrial fibrillation occurs when rapid, irregular electrical signals cause the heart's upper chambers (atria) to beat very fast and irregularly. Atrial flutter is similar but the heart beats fast in a regular pattern. These conditions are diagnosed through electrocardiograms which detect abnormal heart rhythms. Holter monitors and event recorders can also detect arrhythmias over longer periods of time when symptoms occur. Complications include stroke and heart failure, so treatment focuses on rate or rhythm control and preventing clots.
Echocardiography uses ultrasound technology to produce images of the heart. It was pioneered in the 1950s by Drs. Hertz and Edler in Sweden using an ultrasonoscope originally developed for non-destructive testing. Modern echocardiography machines generate ultrasound images using a transducer that transmits sound waves into the body and receives echoes to produce cardiac images. Standard echocardiograms visualize the heart in 2D, M-Mode, and with Doppler modalities from different transducer positions. Echocardiography is used to assess cardiac structure and function, valve abnormalities, wall motion, blood flow, and the presence of pericardial fluid or masses. It provides diagnostic and prognostic information for many cardiac
The second heart sound occurs at the end of systole due to closure of the semilunar valves. There are normally two components: A2 from aortic valve closure and P2 from pulmonary valve closure. A2 is typically louder due to higher pressures in the aorta. The components are normally split, with A2 occurring earlier due to differences in vascular resistance and compliance between the pulmonary and systemic circulations. Widening of the split may indicate conduction delays or pulmonary hypertension. Reversed or paradoxical splitting can occur in conditions that delay left ventricular ejection such as left bundle branch block. Single second heart sounds may result from fusion of the components or absence of one.
Mitral regurgitation (MR) occurs when there is abnormal backflow of blood from the left ventricle into the left atrium during systole. It can be caused by problems with the mitral valve apparatus including the annulus, leaflets, chordae tendineae and papillary muscles. MR is classified as acute, chronic compensated, or chronic decompensated. Chronic MR puts a volume overload on the left atrium and ventricle, leading to dilation and hypertrophy as compensatory mechanisms. However, this can eventually cause reduced cardiac output, pulmonary congestion, and heart failure.
Biatrial enlargement is diagnosed when criteria for both right and left atrial enlargement are present on the same ECG.
The diagnosis of biatrial enlargement requires criteria for LAE and RAE to be met in either lead II, lead V1 or a combination of leads.
The document discusses aortic regurgitation, including its anatomy, etiology, pathophysiology, epidemiology, clinical manifestations, diagnosis, and management. Key points include:
- Aortic regurgitation occurs when the aortic valve fails to close properly, allowing blood to flow back into the left ventricle during diastole.
- Causes include conditions like infective endocarditis, bicuspid aortic valve, hypertension, and Marfan syndrome.
- In acute severe cases, a rapid increase in left ventricular preload can cause pulmonary edema and cardiogenic shock. Chronic cases involve left ventricular dilation and hypertrophy to compensate for the increased preload over time.
- Physical exam may

Valvular heart disease refers to abnormalities of the heart valves that result in obstruction of blood flow or backflow of blood. Echocardiography plays a key role in evaluating valve function and structure non-invasively. Common valvular abnormalities include aortic stenosis, aortic regurgitation, mitral stenosis, and mitral regurgitation. Treatment depends on severity and symptoms, ranging from medical management to surgical repair or replacement of the affected valve.
Mitral stenosis is commonly caused by rheumatic heart disease which leads to inflammation and fusion of the mitral valve leaflets, reducing the mitral valve orifice area. Severe mitral stenosis, defined as a mitral valve area less than 1.0 cm2, can cause pulmonary hypertension, pulmonary edema, atrial fibrillation, and right heart failure as the heart tries to maintain sufficient cardiac output against the back pressure. Physical exam may reveal signs of pulmonary hypertension like a loud pulmonary component to S2, as well as a tapping apex, opening snap, and mid-diastolic rumble on cardiac auscultation. Echocardiography can determine the severity of mitral stenosis and assess
The apical impulse is the point of maximum impulse felt during cardiac examination. In normal systole, it feels like a gentle thrust followed by slight retraction. It is caused by rotation of the left ventricle during contraction and relaxation. Normally it is located on the left side of the chest, less than 10cm from the midline, and occupies less than one intercostal space. Abnormal locations or characteristics can indicate conditions like dilated cardiomyopathy, mitral stenosis, or aortic stenosis.

It then explains different types of heart block including first-, second-, and third-degree heart block and their characteristics as seen on ECG. Treatment options are provided for the various heart block classifications.
Bradyarrhythmias are caused by problems with impulse formation in the sinus node or impulse conduction through the AV node. Sinus node dysfunction can cause sinus bradycardia, sinus pause/arrest, or chronotropic incompetence. Atrioventricular block is classified as first, second, or third degree and may be caused by conditions like CAD, drugs, or infiltrative diseases. Second degree AV block is further classified as Mobitz type I or II based on PR interval characteristics. Third degree AV block causes complete dissociation between atrial and ventricular rhythms.
The document discusses mitral stenosis, including its anatomy, causes, pathogenesis, clinical presentation, investigations and treatments. Some key points:
- Mitral stenosis is a narrowing of the mitral valve opening caused by conditions like rheumatic fever. It reduces blood flow from the left atrium to the left ventricle.
- Symptoms include shortness of breath, cough, fatigue and leg swelling due to increased pulmonary pressures. Examination may reveal an irregular heartbeat and diastolic murmur.
- Echocardiogram can measure the valve area and assess complications. Treatment options range from medical management to surgical procedures like balloon valvuloplasty or valve replacement.

The document concludes with an examination of peripheral pulses and abnormalities of the jugular venous pulse.
This document provides guidelines for managing supraventricular tachycardia (SVT) in adult patients. SVT is defined as a tachycardia with atrial and/or ventricular rates over 100 bpm involving tissue above the His bundle. Common types of SVT include atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reentrant tachycardia (AVRT), atrial tachycardia (AT), multifocal atrial tachycardia (MAT), sinus node reentry tachycardia, and junctional tachycardia. The document reviews the clinical presentation, differential diagnosis, evaluation and treatment of these arrhythmias. It
This document describes techniques for dynamic auscultation of the heart by altering circulatory dynamics through physiological and pharmacological maneuvers. Some key techniques discussed include respiration, postural changes, Valsalva maneuver, isometric exercise, and use of vasoactive agents. Various maneuvers cause changes in heart sounds and murmurs due to effects on hemodynamics, ventricular volumes, and pressures. For example, inspiration augments murmurs on the right side of the heart while expiration accentuates some left-sided murmurs. The Valsalva maneuver and post-premature ventricular contractions also cause characteristic changes heard on auscultation.

This document discusses functional echocardiography for assessing cardiovascular function in neonates. Targeted neonatal echocardiography can be used to evaluate conditions like patent ductus arteriosus, cyanosis, and shock. Functional echocardiography longitudinally assesses cardiac function, blood flows, and shunts. It provides objective evaluation of cardiac output and tissue perfusion that indirect measures cannot. Views used in echocardiography include four-chamber, ductal, and superior vena cava flow views. Superior vena cava flow can estimate systemic blood flow and cerebral blood flow. Functional echocardiography is useful for hypotensive neonates to differentiate causes and guide management.
USMLE CVS 001 Mediastinum anatomy medical chest .pdfAHMED ASHOUR
The mediastinum is the central compartment of the thoracic cavity, located between the lungs.
It is a three-dimensional space that houses various structures within the chest.
The mediastinum extends from the sternum (front of the chest) to the vertebral column (back of the chest) and from the superior thoracic aperture (top of the chest) to the diaphragm (bottom of the chest).
Understanding the anatomy of the mediastinum is crucial for healthcare professionals to interpret diagnostic findings and manage conditions affecting this central compartment of the thoracic cavity.

A chest X-ray is used to examine the lungs, heart, bones and soft tissues of the chest. It involves positioning the body between an X-ray machine and plate. Different tissues absorb X-rays at different levels, appearing white, grey or black, allowing visualization of internal structures. A chest X-ray technician must carefully position the patient and ensure proper inspiration and penetration in order to obtain a high quality image for diagnostic purposes. Key areas that are examined include the heart, lungs, bones, diaphragm and chest wall. Abnormalities may be detected by assessing size, shape, positioning and visibility of anatomical structures.

This document summarizes the CIT-RESOLVE trial which compared an active side branch protection (SB-P) strategy versus a conventional strategy for treating coronary bifurcation lesions at high risk of side branch occlusion, as determined by a V-RESOLVE score of ≥12. The trial randomized 335 patients to the active SB-P group or conventional group. The primary endpoint was side branch occlusion, which occurred less frequently in the active SB-P group compared to the conventional group (9.0% vs 18.0%). Secondary endpoints including periprocedural MI were also lower in the active SB-P group. The study demonstrated that for high risk bifurcation lesions, an active SB-P strategy is superior to
This 40-year-old man presented with night sweats, hemoptysis, dyspnea and weight loss. Imaging showed a cavitary lung lesion and filling defects in the main pulmonary artery suggestive of a pulmonary embolism. Further PET-CT imaging and biopsy revealed primary pulmonary artery angiosarcoma. This is a rare and aggressive malignancy with poor prognosis. Treatment is largely palliative.
This 20-year follow-up study examined the effects of statin therapy initiated in childhood for patients with familial hypercholesterolemia. The study found that statin therapy slowed the progression of carotid intima-media thickness and reduced cardiovascular risks compared to affected parents who did not receive early statin treatment. Specifically, the cumulative risk of cardiovascular events at age 39 was 99% for those treated as children versus 74% for untreated parents. The results support guidelines recommending early statin treatment from ages 8 to 10 years old.
1. Congenital pulmonary stenosis can range from mild to critical severity depending on the right ventricular pressure and pressure gradient across the pulmonary valve.
2. For mild pulmonary stenosis, the natural history is benign and no intervention is typically needed. Moderate stenosis may progress during periods of growth and intervention is considered for gradients over 40-50 mmHg.
3. Balloon valvuloplasty is now the standard intervention for pulmonary stenosis and provides good long-term outcomes, though 20-30% of patients may require an additional procedure.

TSP involves puncturing the interatrial septum to access the left atrium and is used for diagnostic and therapeutic procedures. It requires specialized hardware, understanding of anatomical landmarks and imaging guidance. Potential complications include cardiac perforation, tamponade, thromboembolism, air embolism and atrial septal defects. Special situations like aortic root puncture require abandoning the procedure and monitoring for complications.
This document provides an overview of how to optimize ultrasound imaging settings for different echocardiogram modes. It discusses how to adjust settings like frequency, sector size, and gain for 2D echo; velocity scale, sample volume size, and wall filters for Doppler imaging; and sector size and color baseline for color Doppler imaging. The goal is to provide the best possible contrast and visualize anatomical structures and cardiac function clearly using different echo modes. Settings like focus, depth, and time gain compensation are also covered to enhance image quality.
This document discusses Long QT Syndrome (LQTS), which can be inherited or acquired and causes abnormal prolongation of the QT interval on electrocardiograms (ECGs). It notes that 17 genes have been identified that can cause LQTS, with mutations in potassium channel genes causing about 95% of cases. Symptoms include fainting, seizures, and sudden cardiac death. Risk factors include age, gender, syncope history, QT interval duration, and genetic mutations. Treatment involves lifestyle modifications, beta blockers, and left cardiac sympathetic denervation for high-risk patients. The document concludes with a case study of aborted sudden cardiac death in a patient with Jervell Lange Nielsen Syndrome who was successfully treated with an implantable

Nanogold particles possess unique physical and chemical properties that make them suitable for drug delivery, imaging, and photothermal therapy.
5-hydroxytryptamine or 5-HT or Serotonin is a neurotransmitter that serves a range of roles in the human body. It is sometimes referred to as the happy chemical since it promotes overall well-being and happiness.
It is mostly found in the brain, intestines, and blood platelets.
5-HT is utilised to transport messages between nerve cells, is known to be involved in smooth muscle contraction, and adds to overall well-being and pleasure, among other benefits. 5-HT regulates the body's sleep-wake cycles and internal clock by acting as a precursor to melatonin.
It is hypothesised to regulate hunger, emotions, motor, cognitive, and autonomic processes.
Are you looking for a long-lasting solution to your missing tooth?
Dental implants are the most common type of method for replacing the missing tooth. Unlike dentures or bridges, implants are surgically placed in the jawbone. In layman’s terms, a dental implant is similar to the natural root of the tooth. It offers a stable foundation for the artificial tooth giving it the look, feel, and function similar to the natural tooth.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
Breast cancer: Post menopausal endocrine therapyDr. Sumit KUMAR
Breast cancer in postmenopausal women with hormone receptor-positive (HR+) status is a common and complex condition that necessitates a multifaceted approach to management. HR+ breast cancer means that the cancer cells grow in response to hormones such as estrogen and progesterone. This subtype is prevalent among postmenopausal women and typically exhibits a more indolent course compared to other forms of breast cancer, which allows for a variety of treatment options.
Diagnosis and Staging
The diagnosis of HR+ breast cancer begins with clinical evaluation, imaging, and biopsy. Imaging modalities such as mammography, ultrasound, and MRI help in assessing the extent of the disease. Histopathological examination and immunohistochemical staining of the biopsy sample confirm the diagnosis and hormone receptor status by identifying the presence of estrogen receptors (ER) and progesterone receptors (PR) on the tumor cells.
Staging involves determining the size of the tumor (T), the involvement of regional lymph nodes (N), and the presence of distant metastasis (M). The American Joint Committee on Cancer (AJCC) staging system is commonly used. Accurate staging is critical as it guides treatment decisions.
Treatment Options
Endocrine Therapy
Endocrine therapy is the cornerstone of treatment for HR+ breast cancer in postmenopausal women. The primary goal is to reduce the levels of estrogen or block its effects on cancer cells. Commonly used agents include:
Selective Estrogen Receptor Modulators (SERMs): Tamoxifen is a SERM that binds to estrogen receptors, blocking estrogen from stimulating breast cancer cells. It is effective but may have side effects such as increased risk of endometrial cancer and thromboembolic events.
Aromatase Inhibitors (AIs): These drugs, including anastrozole, letrozole, and exemestane, lower estrogen levels by inhibiting the aromatase enzyme, which converts androgens to estrogen in peripheral tissues. AIs are generally preferred in postmenopausal women due to their efficacy and safety profile compared to tamoxifen.
Selective Estrogen Receptor Downregulators (SERDs): Fulvestrant is a SERD that degrades estrogen receptors and is used in cases where resistance to other endocrine therapies develops.
Combination Therapies
Combining endocrine therapy with other treatments enhances efficacy. Examples include:
Endocrine Therapy with CDK4/6 Inhibitors: Palbociclib, ribociclib, and abemaciclib are CDK4/6 inhibitors that, when combined with endocrine therapy, significantly improve progression-free survival in advanced HR+ breast cancer.
Endocrine Therapy with mTOR Inhibitors: Everolimus, an mTOR inhibitor, can be added to endocrine therapy for patients who have developed resistance to aromatase inhibitors.
Chemotherapy
Chemotherapy is generally reserved for patients with high-risk features, such as large tumor size, high-grade histology, or extensive lymph node involvement. Regimens often include anthracyclines and taxanes.
3. HISTORY
Egyptian physicians and priests employed the technique of
palpation, and it was one of the techniques of the examination in
the ancient Greece.
Practice of precordial palpation was recorded in the Ebers papurus
(1500 BC).
William Harvey (1628) was familiar with the movements of the
chest wall and described, “Motion of the heart”.
Jean Nicolas Corvisart, French physician pioneered the art of
bedside inspection and palpation of the precordium.
4. INTRODUCTION
Precordium: It is the area of the anterior chest overlying the
heart.
cardiac motion is represented by the apex beat or apex impulse,
which is produced by systolic contraction of the left ventricular
free wall and septum.
Right ventricular activity is usually not palpable.
When cardiac hypertrophy or dilatation is present, abnormal
systolic and diastolic events emanating from the left or right
ventricle may be detected on palpation and, on unusual
occasions, left and right atrial impulses may be felt.
8. Examination Technique
Inspection:The subject should be lying comfortably in the
supine position or with the thorax elevated no more than
30 degrees.
Examine the thorax tangentially, first from the foot end of
the bed and then from the patient’s right side directing a
beam of light across the precordium.
9. Palpation of the precordium : is performed from the right side of
the supine patient with the upper trunk elevated to 300 and the
chest completely exposed.
Palpation of the apex should also be done in the left lateral
position, rotated 45–600, which causes the heart to move laterally
and increases the palpability of apex.
10.
11. INSPECTION
Inspection of the anterior chest and precordium includes:
1. Examination of the chest: for its shape, symmetry , position of
the trachea
2. Examination of the precordium for any precordial bulging
3. Scars
4. Retraction
5. Distended vessels over the chest and back
12. 6. Examination of the cardiovascular pulsations
Apex beat
Left parasternal pulsations
Pulsations in the right and left 2nd intercostal spaces (aortic and
pulmonary areas)
Pulsations in the right and left sternoclavicular area
Pulsations in the epigastrium
Pulsations in ectopic areas.
13. Chest abnormalities
The normal chest in an adult is bilaterally symmetrical and
elliptical in cross section
Transverse diameter more than the AP diameter
Shape of the chest Causes
1. Barrel shape COPD
2. Muscular thorax with thin lower
limbs
Coarctation of aorta
3. Shield chest (broad chest) Turner and Noonan syndromes
4. Pigeon chest (pectus
carinatum)
Marfan and Noonan syndromes
5. Funnel chest (pectus
excavatum)
Marfan, Ehler-Danlos, Hunter-
Hurler syndromes and
Homocystinuria
17. Apex beat
DEFINITION - The outermost and lowermost area of definitive
cardiac impulse in early systole, which imparts a perpendicular
gentle thrust to a palpating finger, followed by medial retraction in
the late systole.
Examined for location, extent and retraction
In normal persons there may be a slight retraction of the thorax
medial to the apex impulse
Whereas in hyperdynamic states and LV enlargement this
retraction becomes accentuated and assumes a rocking character.
18. Left Parasternal Pulsations
RV inflow portion underlies the 4th and 5th intercostal space
Outflow portion (infundibulum) lies behind the 3rd left
intercostal space.
In normal adults , RV activity is neither visible nor palpable as
it retracts away from the anterior chest wall during systole.
19. Due to right ventricular
hypertrophy

2. Aneurysm of aorta 2. Thyroidea ima artery
3. Aortic regurgitation 3. thyrotoxicosis
4. Right aortic arch 4.Coarctation of aorta
5. Blalock-Taussig shunt
23. Distended Vessels Over the Chest and Back
1. Veins -Distended veins on the anterior chest wall (with
caudal flow) suggest obstruction of superior vena cava,
while the distended veins with cranial flow indicate inferior
vena caval obstruction.
2. Prominent venous collaterals around the shoulder occur in
subclavian or axillary vein obstruction.
25. 1. Arteries
Collateral vessels may be seen in the interscapular
and infrascapular regions or in the posterior intercostal
spaces and are palpable in patients with coarctation
of aorta, when the patient stands and bends forward
with arms hanging down by the sides (Suzman’s sign).
28. PALPATION
Apical impulse
Position of trachea
Parasternal heave/lift
Thrills
Palpable sounds/shocks
Pulsations
Direction of flow in veins
Tenderness
29. Examination Technique
Palpation of the precordium is performed from the right side of
the supine patient with the upper trunk elevated to 300 and the
chest completely exposed.
Palpation of the apex should also be done in the left lateral
position, rotated 45–600, which causes the heart to move
laterally and increases the palpability of apex.
30. High frequency movements such as ejection sounds, valve
closure sounds, mitral opening sounds and thrills are more
easily detected with the palm and proximal metacarpals held
firmly against the chest.
the low frequency movements such as ventricular diastolic
filling events (S3, S4) are best felt by applying light pressure
with the fingertips.
32. General rule
Finger tips-to feel pulsations
Base of fingers- Thrills
Base of hand
or - Heaves
ulnar aspect
33. Apical impulse
Definition-The outermost and lowermost point of maximum
impulse (PMI)/definitive cardiac impulse in early systole, which
imparts a perpendicular gentle thrust to a palpating finger,
followed by medial retraction in the late systole.
In some patients, the most prominent or "maximal" impulse
may actually reflect ectopic LV motion, right ventricular
activity, or a vascular impulse, all of which are located at sites
distant from the true LV apex impulse.
Retraction is better seen than felt.
34. Mechanism: Anterior and counter clock-wise rotation of LV during
early systole lifts the apex and makes contact with the anterior chest
wall
Intraventricular septum and anterolateral aspect of LV makes
contact with the precordium.
Medial retraction during late systole is due to recoil of the heart as it
rotates clock-wise with the completion of the ejection.
Coincides with opening of aortic valve and beginning of ejection
36. The impulse is sustained for a brief period (up to 0.08 seconds)
and then the outward movement ceases as the LV apex moves
inward
The "true" anatomic LV apex actually is slightly lower and more
lateral than the palpable apical impulse.
37.
38. Features Of Normal Apical Impulse
Gentle , nonsustained tap
Early systolic anterior motion that ends before the last third of systole.
Located within 10 cm of the midsternal line in the 4th/5th ICS / within
7 to 8 cm from the left sternal edge
Palpable Area 0f less than 2.0-2.5 cm2
Detectable in only one ICS
Right ventricular activity normally not palpable
Diastolic events not palpable
May be completely absent in older persons
39. In tall, thin persons, the apex beat can be distal (6th interspace)
and more medial than usual
There may be respiratory alteration in the amplitude of the
apical beat; peak amplitude occur during end expiration
In the left lateral decubitus position the point of chest wall
contact of the apex beat is usually slightly more lateral and
inferior than in the supine position
Character of apex better felt in left lateral decubitus position
An apical impulse of 3 cm in area or greater in the left lateral
position is specific for left ventricular enlargement
40. What to look for
The assessment of the apical cardiac impulse includes:
(1) location-
- Note in which intercostal space the PMI or apex beat is located
- Localize the apical impulse with reference to the midclavicular
line, distance from the midsternum, or relationship to the left
anterior axillary line.
(2) duration-
-The duration of the systolic outward motion is
probably the most important feature of the precordial exam
- sustained apex impulse in the supine position more sensitive than
the EKG in the diagnosis of left ventricular hypertrophy.
41. The critical point to assess is whether or not the impulse "stays up" into the
second half of systole. Proper timing of the apex beat using simultaneous
auscultation of Sl and S2 is essential
(3) size- Any impulse greater than 2 to 2.5 cm in the supine position, or more
than 3 cm in the left decubitus position, represents cardiac enlargement.
(4) force or amplitude- An increase 'in force is consistent with LV hypertrophy
and preserved systolic function
(5) contour - The normal apical impulse consists of a brief, nonsustained anterior
motion in early systole
42.
43. Character of the Apical impulse
The cardiac apex may be:
Absent or feeble
Tapping
Hyperdynamic
Heaving.
44. TAPPING APEX
A shortened outward movement of the apex during early
systole due to the reduced ventricular filling during diastole
gives the apex beat its sharp, short and tapping nature in
mitral stenosis.
Palpable first heart sound
45. Hyperdynamic/hyperkinetic/forceful apex beat
There is an increase in amplitude and duration of excursion of the
apical impulse, but is ill sustained i.e. duration of excursion is less
than 50% of systole with partial lifting of the examining fingers.
In severe volume overload states, particularly with depression of LV
contractility and a decreased ejection fraction, the LV impulse may
become prolonged or sustained into the second half of systole .
This response may be due both to a longer duration of LV ejection
and more globular chamber configuration
46. Heaving/sustained apex beat
There is a sustained increase in amplitude and duration of
excursion( greater than 50% of systole) with sustained lift of
the examining fingers.
The force of contraction is increased, but there is relatively
little chamber dilatation. Thus, the apex impulse is not usually
displaced but has an increased force.
47. VOLUME OVERLOAD PRESSURE OVERLOAD
Increased amplitude without change
in the contour
Increased duration of apical impulse
Downward and outward movement
of apex
Apex undisplaced
Features Heaving Hyperdynamic
Time Increased Normal
Amplitude Increased Increased
Duration >2/3 Of Systole >1/3 to <2/3 Of Systole
Location Occupies One ICS Occupies more than
One ICS

AS,HTN,HCM,coarctati
on Of Aorta
CAD-LV aneurysm,
severe LV dysfunction
Volume Overload-e.g.
AR,MR,VSD,PDA,
High output states
48.
49. VARIATIONS OF THE APICAL IMPULSE
Absent Apical Impulse: Could be due to
Non Cardiac Causes
Behind the rib
Muscular chest wall
Obesity
COPD including emphysema with barrel chest
Left pleural effusion.
Age 50 or over
50. Cardiac causes
Pericardial effusion.
CAD with decreased apical motion
Dextrocardia
Double Apical Impulse
● HOCM (could be double or triple apical impulse)
● LV dyssynergy or LV aneurysm.
53. Displacement of Apical Impulse
Lateral displacement is often due to:
● Skeletal abnormalities: scoliosis, straight back syndrome, marked
pectus excavatum.
● Intrathoracic pathology: massive right-sided pleural effusion,
right-sided pneumothorax, or left lung collapse/fibrosis.
● Eccentric LVH due to mitral regurgitation or aortic regurgitation:
apical impulse is displaced outwards and downwards.
● RVH, e.g. due to mitral stenosis apical impulse is displaced
laterally.
54. LV vs RV Apical Impulse
LV APICAL IMPULSE RV APICAL IMPULSE
Down and outward outward
Localised Diffuse
Retraction noted medial to apex, apex
retracts laterally
Retraction noted lateral to apex, apex
retracts medially
55. Upward displacement
In children; in 4th left intercostal space
Intra-abdominal causes: ascites, massive abdominal tumor,
or advanced pregnancy.
Pericardial effusion: (fluid, first collects in the lower portion
of the pericardial sac.)
Downward displacement
Aortic aneurysm
Mediastinal new growth
56. Right-sided apical impulse
● dextrocardia
● left-sided massive pleural effusion or pnuemothorax and
right lung collapse.
● Skeletal abnormalities such as scoliosis
57. Lateral Retraction of the Apical Impulse (Skoda’s Sign)
● Right ventricular hypertrophy (RVH), when RV occupies the
apex
● Adhesive pericarditis.
(Broadbent’s sign: It is a systolic in-drawing or retraction of 10th
and 11th left intercostal spaces, in the scapular or posterior
axillary line.)
58. Extent of Apical Impulse
Diffuse apical impulse of >3 cm in diameter or apical impulse present
in more than one intercostal space may be due to:
Cardiovascular causes:
Eccentric LVH as in aortic regurgitation
LV aneurysm.
Non-cardiovascular causes:
Subjects with thin chest wall
Hyperdynamic circulation: fever, thyrotoxicosis
Retraction of the lung due to fibrosis or collapse.
59.
60.
61. RV Examination
The movements of the
examining hand and
fingers should be
carefully observed as
the low amplitude RV
activity is better seen
than felt
63. permits the detection of
gentle RV systolic
impulses but also
localizes the
movements to the inflow
portion (4th and 5th
ICS) or to the
infundibulum/outflow
portion (3rd ICS)
64. PARASTERNAL HEAVE/LIFT/IMPULSE
In the normal subject, parasternal activity is usually not detectable
except in young or thin individuals.
Forceful, sustained, or high amplitude parasternal motion is always an
abnormal finding
Right ventricular abnormalities are only detectable in the supine
position.
RV activity is usually low amplitude, it will not be detected without firm
compression.
Held end expiration may be very useful in detecting a subtle or slight RV
lift.
65. AIIMS GRADING OF PARASTERNAL IMPULSE
GRADE I- Visible but not palpable
GRADE II- Visible and palpable and obliterable
GRADE III- Visible and palpable but not obliterable
CAUSES
RV enlargement
Left atrial enlargement
66. GRADE 1
Light objects such as pencil
or scale kept along the
parasternal region, may make
it obvious.
It disappears with the
application of mild counter
pressure.
It is short of systole i.e. ill
sustained,<1/3rd of systole.
1. Normal children and young
adults
2. Thin chest wall
3. Pectus excavatum
67. Grade 2
An obvious lift that can be easily made out.
It disappears/diminishes with the application of moderate
counter pressure.
It is not well sustained i.e.>50% of systole but not throughout
the systole.
It is usually seen in:
– RV volume overload conditions such as tricuspid
regurgitation, ASD, VSD
– Mild-moderate pulmonary hypertension of any cause e.g.
moderate mitral stenosis, left ventricular failure, left to right
shunts (VSD, PDA)
– Moderate-severe mitral regurgitation due to jet/squid effect.
68. MR: Apparent RV impulse due to
systolic expansion of the left atrium
that displaces RV anteriorly. Out of
synchrony with LV apex
PSL occurs in the second half of
systole following S1 and after the
cardiac apex is felt.
It is short in duration (ill sustained)
and more diffused and indicates a
non compliant enlarged left atrium.
69. Dilated Atrium vs RV heave: In the former parasternal pulsation occurs
in the later part of systole after LV impulse is felt; in the later,parasternal
impulse occur together with LV apical impulse and is sustained
throughout systole.
70. GRADE 3
It is a very prominent parasternal lift.
Application of moderate counter pressure does not diminish the
PSL.
It is well sustained i.e. PSL is present throughout the systole and
beyond A2.
Characteristic of RV pressure overload conditions such as:
– Pulmonary stenosis (moderate-severe)
– Severe pulmonary hypertension due to severe mitral stenosis,
left to right shunts (PDA, VSD) and left ventricular failure.
71. No PSL in TOF: There is no PSL in RVH due to TOF
● As it can decompress easily into the overriding of aorta and
through VSD and
● RV is not excessively dilated
73. Palpable Murmurs—Thrills at the Apex
Diastolic or presystolic thrill :
Diastolic thrill of mitral stenosis is highly localized to the apex, which generally
indicates mobile and non-calcified mitral valve.
Systolic thrills:
These are not common at the apex. They may occur due to:
Severe mitral regurgitation especially due to chordal rupture.
Aortic stenosis: Thrill may be traced from 2nd right ICS to the apex and may
get conducted to the carotids. However, it may only be felt at the apex in
calcified aortic stenosis in the elderly patients.
VSD: It is better felt in the 3rd–4th ICS at the left sternal edge.
74. Palpable pericardial rub: It occurs in acute pericarditis and is best
felt at the left sternal border in sitting and leaning forward
positions.
Thrills in tricuspid area
Patient should be in supine position with right lateral rotation.
Occasionally, diastolic thrill of organic tricuspid stenosis and rarely,
systolic thrill of severe tricuspid regurgitation may be palpable.
75. Palpable Murmurs—Thrills In aortic area
● Systolic thrill in the aortic area ccurs in aortic stenosis, which
may be conducted to the carotids.
● Rarely, a diastolic thrill may be palpable due to dilated aortic
root as in Marfan syndrome.
● Palpable diastolic thrill of aortic regurgitation along the left
sternal edge in the 3rd ICS (neo aortic area) perforation or
eversion of an aortic cusp
76. Thrills In pulmonary area
● Systolic thrill in the pulmonary area may be felt in pulmonary
stenosis in sitting and leaning forward positions in held
expiration, while thrill of infundibular pulmonary stenosis is
best felt in the left 3rd ICS.
● Continuous thrill of PDA is felt maximal beneath the left
clavicle, which begins in systole, is reinforced before and after
S2 and proceeds into the diastole without interruption.
● Graham Steel murmur (early diastolic) of high pressure
pulmonary regurgitation may be palpable.
79. Palpable High Frequency Sounds at the Apex
Opening snaps, tumor plops and ejection sounds (clicks) are best felt by
applying firm pressure to the chest with palm and proximal metacarpals
Palpable loud S1: It occurs due to mitral stenosis, tapping type of apex beat
Palpable opening snap: It occurs in early diastole due to mitral stenosis
with pliable mitral valve.
Palpable tumor plop: early diastolic sound due to abrupt decelerationof a
mobile pedunculated LA or RA myxoma as the tumor sits in the mitral or
tricuspid orifice.
Palpable ejection sounds
Ejection sound (click) of congenital aortic stenosis sometimes more readily
palpable over the apex than in the 2nd right intercostal space (ICS).
80. Low frequency sounds
Low frequency sounds such as S3, S4 and pericardial knock are
best felt by light palpation with fingertips in held expiration, but
firm pressure would dampen them.
PALPABLE S3-A palpable S3 is found in patients with a major
elevation in LV filling pressure and LV end-diastolic volume.
Typically, these hearts have a decreased ejection fraction
In subjects with an increased volume and rate of blood flow
crossing the mitral valve, an S3 may be audible and palpable in
the presence of good left ventricular function-MR
81. Palpable LV S3
o Left ventricular failure
o Chronic mitral regurgitation
o Physiological: Children and pregnancy
o Hyperkinetic circulatory states: Anemia, thyrotoxicosis
Palpable pericardial knock:
It occurs in constrictive pericarditis with systolic retraction of
whole of the pericardium especially in the left 10th and 11th
intercostal spaces in the posterior axillary/scapular line
(Broadbent’s sign)
82. Palpable LV S4
Presystolic atrial contraction, felt in the non-compliant LV
when the left ventricular end diastolic pressure (LVEDP) is 15–
18 mmHg.
Palpable S4
1. Aortic stenosis
2. Hypertrophic cardiomyopathy
3. Acute mitral regurgitation and acute
aortic regurgitation
4. CAD- Acute or chronic-Increased diastolic stiffnes
83. Tricuspid area
Palpable Low Frequency Sounds
-RV S3 and S4 may be palpable in inspiration which is
attenuated or even disappears during expiration.
● RV S3 usually indicates RV dysfunction or failure, chronic
severe tricuspid regurgitation and ASD
● RV S4 is associated with pulmonary stenosis, decreased RV
compliance secondary to pulmonary hypertension.
Palpable High Frequency Sounds
Opening snap of organic tricuspid stenosis is sometimes
palpable with the fingers firmly applied in this area or in the
epigastrium.
84. Palpation of Aortic and Pulmonary Areas
Palpated in the sitting and leaning forward positions in held
expiration, which increases the palpability of these areas .
Palpable High Frequency Sounds
In aortic area: Palpable A2 in the aortic area occurs in
● Systemic hypertension, dilated aortic root and moderate aortic
stenosis
● Cyanotic congenital heart disease: When pulmonary trunk is small
as in TOF or when the aortic root is anterior to the pulmonary trunk
as in transposition of greatarteries (TGA).
85. Palpable ejection sound originating in the dilated aortic root.
Ejection sound of congenital aortic stenosis(bicuspid aortic valve) is
sometimes more readily palpable over the apex than in the right 2nd
ICS and should be differentiated from a loud S1.
In pulmonary area
- Palpable P2 in the pulmonary area occurs in pulmonary
hypertension of any cause.
- Palpable ejection sound in the pulmonary area occurs in
pulmonary stenosis during normal expiration.
86. Palpation of Sternoclavicular Areas
Continuous/systolic thrill is palpable on the left side due to Blalock-
Taussig shunt operation, while it is felt on the same side in the modified
shunt operation.
Palpation of Epigastrium
The subxiphoid region, which allows the palpation of RV, should be
examined with the tip of the index finger. It should be done during held
inspiration and in supine position.
While palpating the epigastrium, the pulsations due to RV hypertrophy
are felt by the fingertip, aortic pulsations by the palmar surface and
hepatic pulsations by the lateral surface of the examining index finger.
87.
88. Palpation in the Ectopic Areas
Ectopic LV Impulse
It is usually palpable superior and medial to the normally
expected cardiac apex
Due to dyskinesia of CAD, during the episodes of angina
pectoris or after acute myocardial infarction
Ventricular aneurysm: Persistent paradoxical palpable ectopic
pulsations due to ventricular aneurysm because of myocardial
infarction or trauma.
89. Ectopic LA Impulse
In patients with severe mitral regurgitation with giant LA that
extends to the right, ectopic systolic pulsations of the enlarged LA
may be felt in the right anterior or lateral chest or in the left
axilla.
Ectopic RA Impulse
Normally RA impulse is not visible or palpable.
if RA is enlarged as in tricuspid regurgitation, systolic expansion
of the enlarged RA may be palpable in the entire right lower chest
especially in the 4th right ICS.
Due to PDA Palpable ectopic impulse beneath the left clavicle in
patients with PDA.
95. Hypertrophic Cardiomyopathy
Left ventricular compliance is markedly decreased. Thus, the A
wave typically is very prominent and the left ventricular impulse
is forceful and vigorous
A mid or late systolic secondary "bulge" may be present,
resulting in a double or bifid precordial impulse.
When the A wave is palpable, the precordial motion actually
with be trifid in nature ("triple ripple")
Systolic thrill superior and medial to apex.
96. Cardiomyopathy: Sustained apex,palpable S3,
Presystolic A wave may be palpable
ACS: palpable S4
Old MI: Late systolic motion suggesting LV
dyssynergy
ASD: hyperdynamic RV type apex. Palpable P2
TR: parasternal heave,pulsations in right lower
parasternal area,hepatic pulsation with each
cardiac cycle
