Patterns of spontaneous initiation of AF in isolated-perfused aged hearts exposed to H2O2 (hydrogen peroxide) (0.1 mM) in three different aged hearts. Panel A shows sudden onset of AF arising during sinus rhythm. In panel B, AF starts after a prior transient period of AT at a CL of 120 ms and panel C shows the sudden emergence of AT at a cycle length of 116 ms that last more than 30 sec before degenerating to AF.
