[Other antiarrhythmic agents].

Digitalis decreases the ventricular rates of chronic atrial fibrillation (AF), and is useful in the treatment of patients with AF. Furthermore it is used for atrial flutter and paroxysmal supraventricular tachycardia (PSVT). ATP has been used as a drug of first choice for quick termination of PSVT. In V-HeFT II, the lower mortality in the enalapril arm was attributable to reduction in the incidence of sudden death, probably due to ventricular arrhythmias. Besides, enalapril experimentally increases cardiac refractoriness. In this paper, recent advances in these three drugs are described.
