– Jugular venous pressure
– Examination of central(neck) and peripheral vessels
• Precodial examination
– Inspection

5. Different Valves of the Heart and Normal Blood
Flow

6. Examination of cardiovascular system
• General examination
• Examination of vessels and Blood pressure
– Pulse
– Blood pressure
– Jugular venous pressure
– Examination of central(neck) and peripheral vessels
• Pericardial examination
– Inspection
– Palpation
– Auscultation and
– Percussion??

7. General examination
• Examination of the hands
• Cyanosis(central and peripheral)
• Look for any malformation
• Examination of eye
• Examination of lower extremities

8. Examination - Hands
• Clubbing
• Splinter haemorrhages (infective endocarditis)
• Osler’s nodes (tender)
• Janeway lesions (non-tender)
• Xanthomata (Hyperlipidaemia)

• Examination of abdomen may be important to see
manifestation of cardiac illness
– Tender hepatomegaly
– Pulsatile liver (tricuspid regurgitation)
– Ascites
– Splenomegaly
– Abdominal aortic aneurysm

14. Examination of the Arterial pulse
• Radial artery
• Rate (normal = 60-100)
– Bradycardia (<60)
– Tachycardia (>100)
• Rhythm
– Regular
– Irregular
• Radio-femoral delay (coarctation of the aorta) – comparing radial and femoral
pulse
• Character and volume volume

15. Cont
Radial pulse Other area to check pulse

16. Peripheral Pulses
Dorsalis pedis pulse Posterior tibial pulse

17. Blood Pressure Measurement
• Instrument
– Sphygmomanometer
– Anaeroid and mercury type
• Blood pressure has two component
– Systolic
– Diastolic pressure
• Normal <140/90 mmHg (lower in diabetes)
• Korotkoff sounds
• Use larger cuff width for large arms

• It has different parts
– Cuff
– Bladder

20. SELECTING THE CORRECT BLOOD PRESSURE CUFF
• Width of the inflatable bladder of the cuff should be about
40% of upper arm
• circumference (about 12–14 cm in the average adult)
• Length of inflatable bladder should be about 80% of upper
arm circumference (almost long enough to encircle the arm)
• If anaeroid, recalibrate periodically before use

21. GETTING READY TO MEASURE BLOOD PRESSURE
• Ideally, ask the patient to avoid smoking or drinking caffeinated
beverages for 30 minutes before the BP is taken and to rest for at
least 5 minutes.
• Check to make sure the examining room is quiet and comfortably
warm.
• Make sure the arm selected is free of clothing or any problem on
the hand
• Palpate the brachial artery to confirm that it has a viable pulse.
• Position the arm at the level of heart
• If the patient is seated, rest the arm on a table a little above the
patient’s waist; if standing, try to support the patient’s arm at the
midchest level.

22. How to measure

24. Jugular Venous Pressure
• JVP reflects pressure in the right atrium, or CVP also blood
volume, status of tricuspid valve and diastolic event in RV.
• Best assessed from pulsations in the right internal jugular vein.
• It shouldn’t be done in children < 12 yrs.
• The JVP is the elevation at which the highest oscillation point, or
meniscus, of the jugular venous pulsations is usually evident in
euvolemic pts
• Estimate CVP maximal 3cm from sternal angle + 5cm from atrium
(Right atrial pressure)

25. Jugular Venous Pressure
• Steps
– Position patient 30/45
– Tangential light
– Identify internal jugular venous pulsation(right)
– Extend a long rectangular object or card horizontally from this point
and a centimeter ruler vertically from the sternal angle, making an
exact right angle.
– Measure the vertical distance in centimeters

31. Examination of Heart/Precordium
• Inspection
• Palpation
• Auscultation
• Percussion ???

32. Precordium - Inspection
• Scars
• Chest deformity
– Pectus excavatum
– Pectus carinatum
• Pacemaker box
• Apex beat

33. Precordium - Palpation
• Apex beat
– Location
– Character
• Heaving
• Thrusting
• Double
• Tapping
• Paradoxical
• Left parasternal heave
• Thrills (palpable murmurs)
– Systolic
– Diastolic
• Palpable P2 (pulmonary hypertension)

34. Precordium – Auscultation
Heart Sounds
• Bell – low pitched sounds
• Diaphragm – high pitched sounds
• Mitral Tricuspid Pulmonary Aortic areas
• S1 (first heart sound)
• S2 – Splitting (A2, P2)

36. Precordium – Auscultation
Murmurs
• Timing of murmur
– Systolic
– Diastolic
– Continuous
• Site of maximal intensity
• Loudness
– Grades I-VI
– Thrill
• Pitch
• Radiation
• Dynamic manoeuvres
– Respiration
• Left-sided  on exp.
• Right-sided  on insp.
– Valsalva
– Squatting

37. Heart Murmurs
• Systolic
– Pansystolic
• Mitral regurgitation
• Tricuspid regurgitation
• Ventricular septal defect
– Ejection systolic
• Aortic stenosis
• Pulmonary stenosis
• HOCM
• Atrial septal defect
– Late systolic
• Mitral valve prolapse
• Diastolic
– Early diastolic
• Aortic regurgitation
• Pulmonary regurgitation
– Mid-diastolic
• Mitral stenosis
• Tricuspid stenosis
• Atrial myxoma
• Continuous
– Patent ductus arteriosus
– Arteriovenous fistula
• Pericardial friction rub

38. Heart Murmurs cont….
 Grading of Murmurs
1. Heard only with special effort
2. Soft, but readily detected
3. Prominent, but not loud
4. Loud, usually accompanied by a thrill
5. Very loud (stethoscope angled on chest)
6. Heard with stethoscope off the chest
