General Introduction
To facilitate diagnoses and treatment of cardiac arrhythmias a basic understanding of the physiological cardiac action potential and cardiac conduction system is required.
Cardiac Action Potential
Phase 0: Rapid Depolarization
Phase 1: Early Rapid Repolarization
Phase 2: Plateau
Phase 3: Final Rapid Repolarization
Phase 4: Resting membrane potential
