Abstract

Atrial fibrillation is a complex arrhythmia from both an electrophysiologic and a clinical point of view. As to its electrophysiologic mechanism, three main factors are at work: triggers, initiators, and perpetuators [1,2]. Several triggers have been identified [3-6]: supraventricular reentry tachycardias, atrial extrasystoles, and, more recently, pulmonary vein foci. Possible initiators are Bachmann’s bundle [7] and other critical atrial areas. Finally, the perpetuators are atrial electrophysiologic and anatomic alterations (atrial dilatation, fibrosis, and/or fatty degeneration) which represent the substrate of sustained atrial fibrillation [8,9].
