Sudden cardiac death remains the single most frequent cause of mortality in the industrialized world [1]. Indeed, approximately every 100 s somebody dies suddenly in the United States alone [2]. Most frequently, ventricular fibrillation (VF) associated with acute myocardial ischemia or infarction is the cause of circulatory collapse [1].
When untreated, VF is lethal within minutes because the arrhythmia precludes coordinated contraction of the ventricles and thus causes circulatory arrest. The electrophysiologic mechanism of VF is reentry. Reentrant activation was first described by George Ralph Mines who showed in 1914 that an impulse can travel around a ring of excitable heart tissue and can
