This document contains a series of lectures from Professor Dr. Md Toufiqur Rahman on the topic of Q waves on electrocardiograms (ECGs). The professor defines a Q wave as any negative deflection preceding an R wave, representing normal left-to-right depolarization of the interventricular septum. Small, normal Q waves can be seen in specific left-sided leads. Larger or abnormal Q waves may indicate myocardial infarction or other conditions like cardiomyopathy. Examples of pathological Q waves and their associations with ST segments and T waves are shown from different leads.
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.
Case-1:
A 23 years old medical student presented with occasional palpitation, shortness of breath and chest discomfort. He had the following ECG.
A 53 years old gentleman presented with palpitations for last 5 hours. He is smoker, diabetic, dyslipidemic and hypertensive. He had exertional chest discomfort for last 5 years and did coronary angiogram 3 years back and CAG revealed TVD and advised for revascularization. But he refused and was irregular in medication and reluctant for life style modification. He came to emergency department with this ECG.

Wolff–Parkinson–White syndrome (WPW) is one of several disorders of the conduction system of the heart that are commonly referred to as pre-excitation syndromes. WPW is caused by the presence of an abnormal accessory electrical conduction pathway between the atria and the ventricles. Electrical signals traveling down this abnormal pathway (known as the bundle of Kent) may stimulate the ventricles to contract prematurely, resulting in a unique type of supra-ventricular tachycardia referred to as an atrio-ventricular reciprocating tachycardia.

Survival in patients with advanced heart failure (AHF) has improved over the last 2 decades. An increasing number of patients however, are dying with progressive heart failure over the same duration. Optimal utilization of medical therapies and devices like implantable defibrillators and biventricular pacemakers are the likely reasons patients are surviving longer albeit with progressive HF.
Evolution in mechanical circulatory support (MCS) devices has occurred over the same period, such that they can now be rapidly instituted providing support for pump failure, often percutaneously, with timely restitution of physiologic and metabolic derangements with fewer complications.
MCS devices can be classified as Short term and Long term. Short term devices such as Intraaortic balloon pumps (IABP), Impella ®, TandemHeart® or Venoarterial extracorporeal membrane oxygenation (VA – ECMO) using a Cardiohelp® device, are usually employed as ‘Bridge to Recovery’(BTR) or Bridge to Decision’(BTD), usually in acute settings. Long term devices such as implantable left ventricular assist devices (LVADs) e.g. Heartmate II® & 3®, Heart ware HVAD® are implanted as ‘Bridge to transplant’ (BTT) or ‘Destination therapy’ (DT) usually in patients ‘sliding’ on inotropes when they are transplant eligible (BTT) or ineligible (DT) respectively.
Ventricular assist devices have traditionally been developed for left ventricular support in case of severe left heart or biventricular dysfunction. Historically, right ventricular (RV) dysfunction following LVAD implantation or as a component of biventricular dysfunction was managed with either medical therapy, temporary VADs (i.e. ECMO configuration with continuous flow centrifugal pumps like CentriMag®, Rotaflow ®) or occasionally with LVADs placed on the right side. Recently the Impella RP® and ProtekDuo®, percutaneously placed pumps with inflow in the inferior vena cava & right atrium respectively and outflow in pulmonary artery, have become available as less invasive options, for short term RV support.
The Syncardia® is the only approved total artificial heart system currently in use; however various biventricular, total heart systems (e.g. BiVACOR®) in development show promise.
Mechanical circulatory devices provide attractive, viable, physiologically plausible ventricular support options that can be used effectively in carefully selected patients.

Definition: Cardiac arrhythmias refer to abnormal heart rhythms, where the heartbeat may be too slow (bradycardia), too fast (tachycardia), or irregular.
These irregularities disrupt the normal electrical signaling in the heart.
In a world where hearts beat free and bold,
A silent foe creeps, its story untold,
Rheumatic whispers, in hushed refrain,
A tale of love's struggle, of heartache and pain.
A childhood song, innocent and sweet,
Takes a tragic turn, hearts skip a beat,
Rheumatic winds blow, fierce and unseen,
Leaving scars on hearts that once danced so keen.
Valves that should open, a rhythmic embrace,
Now bear the weight of this silent chase,
Rheumatic echoes, a haunting refrain,
Leaving imprints of sorrow, of loss and of pain.
But amidst the shadows, there's hope that glows,
A symphony of care, compassion bestows,
With knowledge and love, we stand side by side,
To mend these hearts, to be a healing guide.
Rheumatic battles, we'll face them anew,
A united front, a relentless crew,
For every heart deserves freedom's embrace,
And in the face of rheumatic storms, we'll find grace.
So let's raise our voices, let the world hear,
The fight against rheumatic pain, we hold dear,
With courage and faith, we'll rewrite the verse,
A tale of triumph, of hearts that converse.

5. A 5 years old boy presents with fever & swelling of knee and ankle joint for 3 weeks. Write down 3 important D/D. Discuss the treatment of acute rheumatic fever with carditis. (DU-09Ju)
Three important differential diagnoses of a 5-year-old boy presenting with fever and joint swelling for 3 weeks include:
Septic arthritis: This is an acute bacterial infection of a joint that causes similar symptoms to rheumatic fever but is usually monoarticular and associated with more severe pain, redness, and tenderness of the affected joint. Septic arthritis requires urgent drainage and antibiotics.
Juvenile idiopathic arthritis: This is a group of chronic autoimmune disorders that can present with fever, joint swelling, and stiffness. The diagnosis is based on clinical features, laboratory tests, and imaging studies. The treatment may include nonsteroidal anti-inflammatory drugs, disease-modifying antirheumatic drugs, and biologic agents.
Reactive arthritis: This is an inflammatory joint disease that can occur after an infection, especially with certain bacteria such as Chlamydia, Salmonella, or Shigella. Reactive arthritis usually affects the lower limb joints, such as knees, ankles, and feet, and may be associated with skin rash, eye inflammation, or urethritis. The treatment may include antibiotics, nonsteroidal anti-inflammatory drugs, and corticosteroids.
Assuming the diagnosis of acute rheumatic fever with carditis, the treatment usually involves a combination of antibiotics and anti-inflammatory drugs. The antibiotics aim to eradicate the streptococcal infection and prevent further rheumatic fever recurrences, while the anti-inflammatory drugs aim to reduce the inflammation and symptoms of carditis. The specific regimen may vary depending on the severity of carditis, the presence of other complications, and the patient's age and weight. In general, the following principles apply:
Antibiotics: A 10-day course of oral or intramuscular penicillin is the first-line antibiotic for acute rheumatic fever, as it is effective against most strains of streptococci and has low toxicity. Alternative antibiotics may be used for patients who are allergic to penicillin or have recurrent rheumatic fever despite adequate penicillin therapy. Long-term prophylaxis with penicillin is recommended to prevent recurrences, usually until the age of 21 years or for 10 years after the last episode of rheumatic fever, whichever is longer.
Anti-inflammatory drugs: High-dose aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen are usually given for the first 2-3 weeks of acute rheumatic fever to control fever, pain, and inflammation. Corticosteroids such as prednisone or methylprednisolone may be used in severe cases of carditis or when other therapies are not effective or contraindicated. The duration and dose of anti-inflammatory drugs should be tailored to the patient's response and adverse effects, such as gastric
The Cardiovascular System: Life's Vital Transport System
The cardiovascular system, comprising the heart, blood vessels, and blood, is a fundamental physiological network in the body.
It facilitates the circulation of oxygen, nutrients, hormones, and immune cells while eliminating waste products.
Essential for maintaining tissue function, energy production, and overall homeostasis.
Defining the Cardiovascular System
The cardiovascular system, also known as the circulatory system, is a complex network responsible for circulating vital substances throughout the body.
Components of the Cardiovascular System
Heart: A muscular organ that pumps blood, generating the force required to propel blood through the blood vessels.
Blood Vessels: A network of tubes that carry blood to and from various body tissues.
Blood: A specialized fluid containing red and white blood cells, platelets, and plasma, essential for nutrient and gas exchange.
Exploring Applied Physiology of the Cardiovascular System
The cardiovascular system is a cornerstone of human health, regulating the circulation of vital nutrients, oxygen, and waste products throughout the body.
Understanding the applied physiology of this system is essential for healthcare professionals to provide effective medical care and interventions.
Importance of Applied Cardiovascular Physiology
Effective healthcare requires a deep comprehension of how the cardiovascular system functions under various conditions.
Applied physiology knowledge empowers healthcare practitioners to make informed decisions, diagnose disorders, and formulate targeted treatment plans.
Focus on Practical Applications in Healthcare
This presentation delves into the practical aspects of cardiovascular physiology that directly impact clinical practice.
We will explore how physiological concepts are translated into real-world medical scenarios and interventions.
By grasping the applied physiology of the cardiovascular system, healthcare providers can optimize patient care, enhance diagnostics, and improve treatment outcomes.
Throughout this presentation, we'll bridge the gap between theoretical understanding and its practical implications in the field of healthcare.
Understanding the Components
The cardiovascular system comprises three crucial components: the heart, blood vessels, and blood.
Heart: A muscular organ that pumps blood, ensuring a continuous flow throughout the body.
Blood Vessels: A network of tubes that transport blood to and from various tissues.
Blood: A specialized fluid that carries nutrients, oxygen, hormones, and removes waste products.
Role in Oxygen and Nutrient Delivery
Oxygen from the lungs and nutrients from the digestive system are transported to body tissues through the bloodstream.
These essential components are required for cellular metabolism and energy production.
Peripartum cardiomyopathy (PPCM) is a type of heart disease that affects women during the last month of pregnancy or in the first few months after delivery. It is characterized by a weakened and enlarged heart muscle, which makes it difficult for the heart to pump blood efficiently to the rest of the body. The exact cause of PPCM is unknown, but it is believed to be related to the hormonal changes and increased demands on the heart that occur during pregnancy. Symptoms of PPCM can include shortness of breath, fatigue, chest pain, swelling in the legs and feet, and palpitations. Treatment for PPCM usually involves medications to improve heart function and supportive care to manage symptoms. In severe cases, advanced treatments such as implantable devices or heart transplantation may be necessary. With early diagnosis and treatment, most women with PPCM can recover completely and go on to lead healthy lives.during pregnancy.
The diagnosis of PPCM is based on clinical symptoms, such as shortness of breath, fatigue, chest pain, and edema, along with imaging studies, such as echocardiography. Treatment for PPCM usually involves medications to improve heart function and supportive care to manage symptoms. These medications can include beta-blockers, ACE inhibitors, diuretics, and inotropic agents. In severe cases, advanced treatments such as mechanical circulatory support or heart transplantation may be necessary.
The prognosis for PPCM varies depending on the severity of the disease and the presence of underlying comorbidities. However, with early diagnosis and appropriate treatment, most women with PPCM can recover completely and go on to lead healthy lives. The recurrence rate of PPCM in subsequent pregnancies is approximately 20%, and women who have had PPCM are advised to avoid future pregnancies or undergo careful monitoring and management during pregnancy.
There are still many unanswered questions about PPCM, including its exact cause, optimal diagnostic and treatment strategies, and long-term outcomes. Further research is needed to better understand this complex and potentially life-threatening condition.
In conclusion, PPCM is a rare but serious form of heart disease that can occur during or after pregnancy. Early recognition and management of this condition are critical in preventing complications and improving outcomes for both the mother and the baby. Future research will continue to shed light on the pathophysiology and optimal management of PPCM.

Q wave
Professor Dr Md Toufiqur Rahman
The Q Wave
• A Q wave is any negative deflection
that precedes an R wave
• The Q wave represents the normal left-
to-right depolarisation of the
interventricular septum
• Small ‘septal’ Q waves are typically seen
in the left-sided leads (I, aVL, V5 and V6)

28.11.2019 CMMC-02 ECG Lecture 08
Q wave
Professor Dr Md Toufiqur Rahman
Q waves in different leads
• Small Q waves are normal in most
leads
• Deeper Q waves (>2 mm) may be seen
in leads III and aVR as a normal variant
• Under normal circumstances, Q
waves are not seen in the right-sided
leads (V1-3)

Q wave
Professor Dr Md Toufiqur Rahman
Pathological Q Waves
Q waves are considered pathological if:
> 40 ms (1 mm) wide
> 2 mm deep
> 25% of depth of QRS complex
Seen in leads V1-3
Pathological Q waves usually indicate
current or prior myocardial infarction.

Q wave
Professor Dr Md Toufiqur Rahman
Differential Diagnosis/ Causes of Q waves
• Myocardial infarction
• Cardiomyopathies —
Hypertrophic (HCM), infiltrative myocardial
disease
• Rotation of the heart — Extreme clockwise
or counter-clockwise rotation
• Lead placement errors — e.g. upper limb
leads placed on lower limbs

Professor Dr Md Toufiqur Rahman
Loss of normal Q waves
• The absence of small septal Q
waves in leads V5-6 should be
considered abnormal.
• Absent Q waves in V5-6 is most
commonly due to LBBB.
