The antiarrhythmic effect of the cardioselective beta-adrenoreceptor blocking agent metoprolol, given intravenously, was studied in 20 patients with acute supraventricular tachyarrhythmias, including patients with congestive heart failure, acute myocardial infarction and complete bundle branch block. Six patients out of 9 with atrial fibrillation reverted to sinus rhythm. In all patients with atrial tachycardia and 3 out of 4 patients with atrial flutter restoration of sinus rhythm occurred. The drug was well tolerated and is of clinical value for the treatment of supraventricular tachyarrhythmias even in an elderly patient group.
对20例急性室上性心律失常患者（包括充血性心力衰竭、急性心肌梗死和完全性束支传导阻滞患者）进行了研究，观察静脉注射心脏选择性β-肾上腺素能受体阻滞剂美托洛尔的抗心律失常作用。9例心房颤动患者中有6例恢复为窦性心律。所有房性心动过速患者以及4例心房扑动患者中有3例恢复为窦性心律。该药物耐受性良好，即使在老年患者组中，对治疗室上性心律失常也具有临床价值。
