心电图V_2V_6导联T波差值对诊断正后壁心肌梗塞的价值

The Clinical Significance of Tv_2—Tv_6 by ECG in the Diagnosis of Posterior Myocardial Infarction

急性心肌梗塞(AMI)是一种好发于老年人的严重疾病,而在常规十二导联心电图分析中正后壁心肌梗塞(SPMI)容易漏诊。对我院冠心病监护病房(CCU)近6年来有完整资料的320例病人的心电图进行回顾性分析,并比较V_1导联R/S≥1与V_2、V_6导联T波幅值差达到0.38mV(下简称Tv_2-Tv6≥0.38mV)两指标对诊断SPMI的价值。结果提示:Tv_2-Tv_6≥0.38mv是一个更有价值的诊断指标。

Acute myocardial infarction is one of the serious diseases which affect the elder. Posterior-wall acute myocardial infarction is often missed by Routine 12-lead ECG. We have retropectiveiy analysed the ECGs of 320 patients with intact data treated in our CCU in the past 6 years. R/S≥l in V_1Was compared with TV_2-v_6≥0. 38 mV in the diagnosis of posterior myocardial infarction. The result indicated that TV_2-Tv_6≥0. 38 mV was a better diagnostic parameter.
