The electrophysiologic mechanisms reviewed in this article include: automaticity of pacemaker fibers, transformation of nonpacemaker into pacemaker fibers, "injury" currents and reentry.

Atrial Fibrillation

Emergency Medicine Clinics of North America, 2011
Atrial fibrillation (AF) results from the chaotic depolarization of atrial tissue and is the most common dysrhythmia diagnosed in United States (US) emergency departments. AF affects greater than 1% of the general population, with a peak prevalence of 10% in those greater than 80 years of age. By 2050, it is estimated that nearly 16 million US patients

European Heart Journal, 1994
We report the case of a patient who developed spontaneously a ventricular fibrillation during atrial fibrillation, 8 min after a perfusion of isoproterenol was stopped. Two mechanisms could explain the ventricular arrhythmia: silent ischaemia and a long-short cycle sequence just before ventricular fibrillation.
