Propranolol was found to be a useful drug in the treatment of acute tachyarrhythmias. Forty-three episodes in 34 patients were successfully treated and sinus rhythm restored by using intravenous propranolol. All patients had recent myocardial infarctions complicated by mild, moderate, or severe left ventricular failure. It was judged that the net balance between the negative inotropic and chronotropic properties of propranolol on the myocardium resulted in a clinical improvement. A side effect in a few patients was sinus bradycardia which responded promptly to atropine sulfate or isoproterenol.
