Abstract
Cardiac electrophysiology has rapidly moved from the mapping and ablation of accessory atrioventricular connections and ectopic foci to more extensive mapping and substrate modification. Training in cardiac electrophysiology requires a detailed knowledge of the anatomy and physiology of the heart. In order to understand the basis of cardiac electrophysiology it is important to discuss the different phases of the cardiac action potential, variability in morphology and duration throughout the heart and the most important ion channels and electrolyte shifts responsible for depolarization and repolarization of the cardiac cells. Electrophysiology continues to rely heavily on an understanding of these basic principles as well as the relevant anatomy of all cardiac chambers and surrounding structures. It is therefore fundamental to have a thorough understanding of cardiac anatomy as visualized on fluoroscopy, echocardiography, CT, MRI and three-dimensional cardiac mapping systems.
