[Treatment of intra- and postoperative cardiac tachyarrhythmias with the new calciumantagonist Ro 11-1781 (author's transl)].

30 patients with cardiac tachyarrhythmias were treated intra- and postoperatively with the new calciumantagonist Ro 11-1781. Atrial fibrillation, paroxysmal supraventricular tachycardia, supraventricular and ventricular extrasystoles and atrial tachycardia were the main indications. A good antiarrhythmic effect was noticed, provided that a dose of not less than 1 mg/kg was given. The mean fall of blood pressure was 4%, the maximal fall 15%.
