近年来,急性心肌梗塞(AMI)时QTc延长的临床意义愈来愈受到重视,但QTc延长到估测AMI时严重室性心律失常、心源性猝死的价值目前仍有争议。本文的目的在于通过对60例AMI的QTc的分析,探讨QTc延长与AMI的临床及预后的关系。 资料和方法 一、对象 本文收集了我院1980～1990年发病后当日急诊入院的AMI患者临床心电图(ECG)资料,且去除严重的电解质紊乱和入院前应用影响
In recent years, the clinical significance of QTc prolongation in acute myocardial infarction (AMI) has received more and more attention. However, the value of QTc prolongation to severe ventricular arrhythmia in estimating AMI is still controversial. The purpose of this article is to investigate the relationship between QTc prolongation and the clinical and prognostic significance of AMI by analyzing QTc in 60 patients with AMI. Materials and Methods I. Object This article collected clinical ECG data of AMI patients admitted to our hospital from the emergency day after their onset from 1980 to 1990 and removed severe electrolyte disturbances and pre-admission effects
