Antiarrhythmic effects of HOE642, a novel Na +-H + exchange inhibitor, on ventricular arrhythmias in animal hearts
HOE642 (4-isopropyl-3-methylsulphonylbenzoyl-guanidine methanesulphonate), a novel Na +-H + exchange subtype 1 inhibitor, was investigated for its possible antiarrhythmic effects on coronary artery ligation/reperfusion and ouabain-induced arrhythmias in the canine heart which may occur after intrace...

HOE642 at the same dose markedly reduced the total duration and the incidence of reperfusion-induced ventricular tachycardia, and the incidence and mortality of reperfusion-induced ventricular fibrillation in rats (ventricular tachycardia duration, 159±12 s to 21±8 s,
