Study Notes
ECG Bundle Branch Block
-
William Marrow Mnemonic:
- LBBB: 'W' shape in V1 (wide, notched QRS) and 'M' shape in V6 (M-shaped QRS)
- RBBB: 'M' shape in V1 (RSR' pattern) and 'W' shape in V6 (wide S wave)
Heart Murmurs
- Diastolic Murmurs: Affected by specific heart sounds.
- Systolic Murmurs: Differentiated by distinct heart sounds.
Heart Disease Prevention
- Risk Factors: Categorized into primary (preventative) and secondary (after diagnosis) prevention.
Dilated Cardiomyopathy
- Description: Myocardial disorder without coronary artery disease, hypertension, or significant valvular/congenital defects.
-
Etiology:
- Familial (25% prevalence, mostly autosomal dominant)
- Idiopathic (unclear causes)
- Secondary causes (e.g., myocarditis, chronic alcohol use)
- Morphology: Characterized by myocardial damage, interstitial fibrosis, and reduced systolic function.
Symptoms and Diagnostics
- Symptoms: Progressive condition; asymptomatic initially leading to heart failure signs like fatigue and dyspnea.
-
Diagnostics:
- ECG: Left bundle branch block, atrial fibrillation, ventricular arrhythmias.
- Imaging: Echocardiography; shows dilated cavities and mitral/tricuspid regurgitation, assessed via CMR.
- Laboratory Tests: Include NTproBNP to assess heart failure.
Complications of Dilated Cardiomyopathy
- Intracardiac Thrombus: Risk in left ventricle and atrial appendage.
- Arrhythmias: Including atrial fibrillation and malignant arrhythmias.
- Heart Failure Progression: Potential decompensation leading to severe outcomes.
Therapy for Dilated Cardiomyopathy
- Goals: Slow progression, alleviate symptoms, reduce mortality.
- ICD Recommended: Particularly for secondary prevention.
- Primary Prevention: Symptomatic heart failure management, ejection fraction considerations.
Ventricular Arrhythmias
- Key Features: Epsilon wave indicates arrhythmias; can be non-sustained or sustained VT.
- Diagnosis: Family history and imaging criteria for ARVC must meet specified criteria.
Restrictive Cardiomyopathy
- Etiology and Forms: Commonly associated with amyloidosis.
- Imaging Findings: Echo shows concentric hypertrophy and diastolic dysfunction.
- Sign: "Ground-glass" appearance in cardiac MRI indicating diffuse myocardial enhancement.
Tako-tsubo Cardiomyopathy
- Description: Reversible left ventricular dysfunction, often following emotional or physical stress (commonly in postmenopausal women).
- Signs and Symptoms: Chest pain, ST elevation, and positive cardiac biomarkers similar to ACS.
Acute and Chronic Heart Failure
- Acute Heart Failure: Symptoms include significant hemodynamic changes, diagnostic assessments vital.
- Chronic Heart Failure: Problems develop over time; diagnostics essential to management.
Infective Endocarditis
- Key Considerations: Diagnostic and clinical management based on symptoms and causative organisms.
Valvular Heart Diseases
- Aortic Stenosis and Insufficiency: Diagnosis involves clinical presentation and imaging studies.
- Mitral Valve Stenosis and Insufficiency: Symptoms and diagnostic challenges outlined.
Congenital Heart Disease
- Atrial and Ventricular Septal Defects: Clinical features and imaging are essential for diagnosis.
Hypertension Management
- Etiology and Diagnosis: Understanding underlying causes and proper diagnostic tests.
- Treatment Strategies: Focus on lifestyle and pharmacological interventions.
Ischemic Heart Disease
- Forms: Includes silent ischemia, CHF, stable angina, and acute coronary syndrome.
- ACD without ST Elevation: Distinct phases require careful monitoring and management.
Heart Failure Treatment Strategies
- Advanced Support Measures: Utilize vasopressors, inotropic support, and advanced mechanical circulatory support when necessary.
- Complications Monitoring: Vigilant for mechanical complications like mitral papillary rupture or ventricular septal rupture.
Angina Pectoris
- Causes: Decreased oxygen supply and increased demand lead to chest pain.
- Diagnosis: Determines unstable angina presentation and employs a multifaceted diagnostic approach.
Risk Profile Evaluation
- Use of Biochemical and Imaging Techniques: Identifying potential risk factors (e.g., diabetes, hyperlipidemia) to guide management plans.
