摘　　要：目的评析在冠状动脉粥样硬化性心脏病(冠心病)患者诊断中心电图检查的临床应用价值。方法选取该院2014年4月‐2015年6月收治的冠心病患者78例,所有患者均行冠状动脉造影检查和心电图检查,对两种诊断方法的准确率、假阴性率、假阳性率及特异度进行对比。结果结果显示,准确率为59.26%,假阴性率为40.74%,特异度为54.17%,假阳性率为45.83%,心电图对冠心病诊断多支病变的正确率明显高于单支病变的正确率(P<0.05)。结论在冠心病患者诊断中采用心电图检查有较高的准确率,且有较高的假阳性率,而且对于多支病变及单支病变的诊断具有一定的临床诊断价值。[Objective] To analyze the clinical value of electrocardiogram （ECG） examination in the diagnosis of coronaryheart disease （CHD）. [Methods] Seventy-eight cases of coronary heart disease patients treated in our hospital from April 2014 to June 2015 were selected, and coronary angiography examination and electrocardiogram inspection were performed in all patients. The accuracy rate, false negative rate, false positive rate and specificity rate of the two diagnostic methods were compared. [Results] In the diagnosis of coronary heart disease with electrocardiogram, the accuracy rate was 59.26%, the false negative rate was 40.74%, the specificity rate was 54.17%, and the false positive rate was 45.83%. The accuracy rate of electrocardiogram in diagnosing multivessel lesions of coronary heart disease was obviously higher than that in diagnosing single lesion （P 〈0.05）. [Conelusion] ECG examination has a relatively high accuracy and false positive rate in the diagnosis of coronary heart disease, and has a certain clinical diagnostic value for multivessel lesions and single lesion.
