Content Outline
PreviewUnit 1631: Comprehensive Cardiology
1. Anatomy of the Heart
- Structure of the heart
- Four chambers: right atrium, right ventricle, left atrium, left ventricle
- Heart valves: tricuspid, pulmonary, mitral (bicuspid), aortic
- Major blood vessels: superior & inferior vena cava, pulmonary arteries & veins, aorta
- Conduction system
- Sinoatrial (SA) node
- Atrioventricular (AV) node
- Bundle of His and Purkinje fibers
- Functions of each component
2. Cardiac Cycle
- Overview of one heartbeat sequence
- Phases
- Diastole: ventricular relaxation and filling
- Atrial contraction (atrial systole)
- Ventricular contraction (ventricular systole)
- Valve mechanics
- Opening and closing of atrioventricular and semilunar valves
- Correlation with heart sounds
3. Electrocardiography (ECG)
- Basics of ECG recording
- Wave components
- P wave: atrial depolarization
- QRS complex: ventricular depolarization
- T wave: ventricular repolarization
- Interpretation of ECG
- Normal sinus rhythm
- Common abnormalities: arrhythmias, ischemia, infarction indicators
4. Common Cardiac Disorders
- Coronary artery disease (CAD)
- Causes and pathophysiology
- Symptoms and complications
- Heart failure
- Types: systolic vs diastolic
- Clinical features
- Arrhythmias
- Types (e.g., atrial fibrillation, ventricular tachycardia)
- Causes and effects
- Valvular heart disease
- Stenosis and regurgitation
- Impact on heart function
- Diagnostic tests overview
- Treatment options
5. Pharmacology in Cardiology
- Antiplatelets (e.g., aspirin)
- Beta-blockers
- ACE inhibitors
- Diuretics
- Antiarrhythmics
- Mechanisms of action
- Indications and contraindications
6. Diagnostic Procedures in Cardiology
- Echocardiography
- Types: transthoracic, transesophageal
- Applications
- Stress testing
- Exercise and pharmacologic stress tests
- Cardiac catheterization
- Procedure and diagnostic value
- Cardiac MRI
- Imaging benefits and indications
7. Cardiac Rehabilitation
- Purpose and goals
- Components
- Exercise training
- Nutritional counseling
- Psychological support
- Outcomes and quality of life improvements
8. Preventive Cardiology
- Lifestyle modifications
- Diet and nutrition
- Physical activity
- Smoking cessation
- Blood pressure management
- Cholesterol control
- Risk assessment and monitoring
9. Pediatric Cardiology
- Congenital heart defects
- Common types and presentations
- Acquired heart diseases in children
- Diagnostic and treatment considerations
- Specialized pediatric cardiac care
10. Emerging Trends in Cardiology
- New technologies
- Wearable cardiac monitors
- Advances in imaging
- Research and clinical trials
- Novel treatment modalities
- Updated clinical guidelines
