amiodarone was administered in five patients with life-threatening ventricular arrhythmias resistant to other antiarrhythmic agents : suppression was obtained in one of two patients with recurrent ventricular tachycardias and control was achieved in three patients with repetitive ventricular tachycardia and ventricular fibrillation , allowing the effective use of intra-aortic balloon counterpulsation ( iabp ) needed for hemodynamic support .
