Heart Failure, Rhythm & Valve Disease

Recognize congestion and impaired output, interpret rhythm patterns and connect murmurs to hemodynamics.

FULL CHAPTER EXPLANATION

Deep Learning — Module 04

Connect symptoms and examination findings to a differential, targeted investigations, initial priorities and reassessment.

01

Heart failure syndrome

Heart failure is a clinical syndrome resulting from structural or functional cardiac abnormality. Breathlessness, fatigue, orthopnea and edema can suggest it but are not specific. Examine perfusion, jugular venous pressure, lungs and peripheral edema, and look for precipitants such as ischemia, infection, arrhythmia or medicine interruption. Both reduced and preserved ejection fraction can occur. A normal ejection fraction alone therefore does not exclude the syndrome.

02

Investigation and continuing care

ECG, natriuretic peptides, chest imaging and echocardiography answer complementary questions. Natriuretic peptide concentrations are influenced by other conditions and patient factors; echocardiography evaluates structure, valves and function. Management addresses congestion, the underlying cause and disease-modifying treatment appropriate to phenotype and clinical status. Renal function, electrolytes, blood pressure and adherence need review. Education and follow-up reduce avoidable decompensation and should include when to seek urgent help.

03

Rhythm assessment

Assess symptoms and stability before naming the rhythm. Rate, regularity, atrial activity and QRS width provide a framework for ECG interpretation. Palpitations with syncope, chest pain, shock or severe breathlessness need urgent assessment. Atrial fibrillation typically has an irregular ventricular response without consistent discrete P waves; an ECG is needed for confirmation. Stroke-prevention decisions require individualized thromboembolic and bleeding-risk assessment, not rate alone.

04

Bradycardia and conduction

A slow pulse may be physiological or related to drugs, conduction disease, metabolic disturbance or ischemia. Correlate it with symptoms and perfusion and review reversible causes. A broad-complex tachycardia in an unwell patient is potentially dangerous and requires an emergency rhythm pathway. Do not assume that a prior history of anxiety explains current palpitations. Check medicines and electrolytes because treatment itself can alter conduction and repolarization.

05

Valves and infection

Describe a murmur by timing, site, radiation and associated signs; intensity does not reliably grade every lesion. Echocardiography defines anatomy and severity when indicated. Fever with risk factors, embolic features or a new regurgitant murmur raises concern for infective endocarditis. Appropriate blood cultures and imaging support diagnosis, but urgent care should reflect stability. Rheumatic valve disease remains relevant and connects prior disease, valve complications and continuing preventive care.

High-Yield Revision

  • Preserved ejection fraction does not exclude heart failure.
  • Assess rhythm stability before detailed classification.
  • A murmur needs context and appropriate imaging.

Common Exam & Concept Pitfalls

  • Do not diagnose atrial fibrillation from pulse palpation alone.
  • Do not treat murmur loudness as a universal severity scale.
