Abstract
Electrophysiological and antiarrhythmic effects of a novel class III a ntiarrhythmic drug nibentan were studied in 10 patients with paroxysma l ventricular tachycardia. After intravenous injection of nibentan (0, 125 mg/kg) prolongation of QT and QT(c) intervals, significant increas es of right atrial, right ventricular and His-Purkinje system's effect ive refractory period were observed. Antiarrhythmic activity of nibent an in relation to reproducible at endocardial pacing paroxysmal ventri cular tachycardia was 80%. In 1 patient arrhythmogenic effect of the d rug - polymorphic ventricular tachycardia (torsade de pointes) - was r egistered.
