  1. Induction parameters represent minimal cycle lengths of basic stimuli and up to five extrastimuli (S1-5). In each animal was EP protocol made three times. HR indicates heart rate; ERP, effective refractory period of ventricles; VF, ventricular fibrillation; NS,statistically non-significant; **P < 0.01; P ***P < 0.0001.
