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

Cardiac conduction

Sinus node

Atrium

AV node

Bundle of His

Bundle Branches and Purkinje fibers

Venticle

Mechanisms of Arrhythmia

Abnormal Impulse Formation

Abnormal Automaticity

Triggered Activity

Early Afterdepolarizations

Delayed Afterdepolarizations

Disorders of Impulse Conduction
