verapamil added during reoxygenation reduced the incidence of reoxygenation arrhythmias and ventricular fibrillation ( 47 % and 29 % , n = 17 , p less than 0.01 and p less than 0.05 vs. controls , respectively ) but it had no effect on programmed stimulation-induced ventricular fibrillation ( 100 % , n = 10 ) .
