Figure 2 Simultaneous recordings of the electrocardiogram (ECG) and the monophasic action potential (MAPs) in the right ventricular outflow tract (RVOT) and right ventricular apex (RVA) during failed induction of ventricular fibrillation (VF). Post-shock repolarization time (PSRT) is 110 ms in the RVOT; PSRT is 95 ms in the RVA. The post-shock dispersion repolarization (PSDR) is 15 ms. The T wave shock generated one ventricular beat with no VF induction.
