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 (AMI) is a serious disease predisposed to the elderly, whereas posterior wall myocardial infarction (SPMI) is often missed by routine 12-lead ECG analysis. The electrocardiogram of 320 patients with complete data of coronary heart disease unit (CCU) in our hospital for the past 6 years were retrospectively analyzed. The difference of T wave amplitude between R / S≥1 and V_2, V_6 leads of V_1 lead was 0.38 mV (hereinafter referred to as Tv_2-Tv6 ≥ 0.38mV) two indicators of the value of the diagnosis of SPMI. The results suggest that: Tv_2-Tv_6 ≥ 0.38mv is a more valuable diagnostic indicator.
