[Ambulatory treatment of paroxysmal supraventricular arrhythmias with verapamil (isoptin)].

Twenty patients, seven of them with paroxysmal supraventricular tachycardia; 8 with paroxysmal auricular flutter; 3 with paroxysmal auricular fibrillation and 2 with paroxysmal atrial tachycardia, with stage II of A-V block, were treated intravenously with isoptin, with an average dose of 0.1 mg/kg body mass. Ten, out of them, restored their sinus rhythm, 7 considerably slowed down the heart rate and 3 failed to respond. Adverse effects were observed only in one patient--transitory hypotension.
