室性早搏(VPC)是心肌梗死(MI)存活病人死亡的独立危险因素。本文报告胺碘酮对比美托洛尔或无特殊治疗,对AMI伴左室功能减低和无症状性VPC病人的异位搏动及预防死亡的作用。对象和方法共368例,发生AMI后10～60天,左室射血分数0.2～0.45,动态心电图示平均≥3个VPC/h、成对或成串(<15次)VPC的病人。随
Ventricular premature beats (VPC) are independent risk factors for the death of patients with myocardial infarction (MI). This article reports the effects of amiodarone versus metoprolol or no treatment on ectopic beats and mortality in AMI patients with left ventricular dysfunction and asymptomatic VPC. Subjects and Methods A total of 368 patients, AMI after 10 to 60 days, left ventricular ejection fraction of 0.2 to 0.45, the average number of ambulatory ECG ≥ 3 VPC / h, paired or series (<15) VPC patients.
