Comprehensive Guide to Cardiac Electrophysiology (Handwritten Notes)
Cardiac electrophysiology forms the foundation of understanding heart rhythm disorders and their management. These handwritten notes provide detailed insights into the electrical activity of the heart and its clinical implications.
Key Components of Cardiac Electrophysiology
- Action Potential Phases:
- Phase 0: Rapid depolarization (Na+ influx)
- Phase 1: Early repolarization (K+ efflux)
- Phase 2: Plateau phase (Ca2+ influx)
- Phase 3: Repolarization (K+ efflux)
- Phase 4: Resting membrane potential
- Cardiac Conduction System:
- SA node pacemaker activity
- AV node delay mechanism
- Bundle of His and Purkinje fibers
Ion Channels and Their Roles
- Voltage-gated sodium channels (Phase 0)
- L-type calcium channels (Phase 2)
- Potassium channels (Phases 1, 3)
- Funny channels (Pacemaker potential)
ECG Correlations
- P wave: Atrial depolarization
- QRS complex: Ventricular depolarization
- T wave: Ventricular repolarization
- PR interval: AV conduction time
Clinical Applications
- Mechanisms of arrhythmias
- Re-entry circuits
- Triggered activity
- Automaticity disorders
- Antiarrhythmic drug actions
- Pacemaker functioning principles
