in pigs prazosin reduced the incidence of ventricular premature depolarizations during occlusion and propranolol reduced the incidence of both ventricular premature depolarizations and ventricular tachycardia during occlusion , but the incidence of ventricular fibrillation was not significantly reduced in the prazosin- and propranolol-treated pigs .
