V_2V_6导联T波差值对正后壁心梗的诊断价值

The clinical significance of Tv_2 -Tv_6 by ECG in the dagnosis of posterior myocardial infarction

AMI是一种多发于中老年人的严重疾病,在常规十二导联EKG分析中,正后壁心梗容易漏诊,本文对我院近11年来有完整资料的328例病人EKG进行回顾性分析,并比较V_1导R/S>1与V_2、V_6导T波波幅差值达到0.38mv两指标对诊断正后壁心梗的价值,结果提示TV_2—TV_6≥0.38mv是一个更有诊断价值的指标。

Aente myoeardial infarction is one of the serious diseases which affect tke elder, posterior-wall acute myocardial infarction is often missed by routine 12-lead BCG. fe retropeetively analysed ECG of 320 patients with intact data who were treated in our hospital in the past 11 years. R/S> 1 in v1 was compared with Tv2-Tv6>0. 38mv in the diagnosis of posterior myocardial infarction. The result indicated that Tv2-Tv6>0. 38mv was a better diagnostic parameter.
