本文在８０例老年人中以冠状动脉造影结果为标准，评价了静息１２导联心电图（ＥＣＧ）、２４小时动态心电图（Ｈｏｌｔｅｒ）、二维超声心动图（ＵＣＧ）及心肌核素显像平衡法（ＥＭ）在老年冠心病诊断中的价值。结果显示，上述方法的诊断敏感性、特异性、阳性预测值及诊断指数分别是：ＥＭ为９１．２％、８８．９％、９６．９％、８０．１％；ＥＣＧ为９１．５％、４４．４％、９２．９％、３５．９％；ＵＣＧ为４８．３％、７７．８％、９３．５％、２５．８％；Ｈｏｌｔｅｒ为６６．７％、１６．７％、８１．５％、１６．６％。４种无创性静息检查方法中，ＥＭ诊断指数最高，其次为ＥＣＧ。 In this paper, 80 elderly patients with coronary angiography as the standard evaluation of the resting 12-lead electrocardiogram (ECG), 24-hour Holter, two-dimensional echocardiography (UCG) and myocardial imaging imaging balance Value of Law (EM) in the Diagnosis of Elderly Coronary Heart Disease. The results showed that the diagnostic sensitivity, specificity, positive predictive value and diagnostic index of the above methods were: EM 91.2%, 88.9%, 96.9%, 80.1%; ECG 91.5% , 44.4%, 92.9%, 35.9% respectively; UCG was 48.3%, 77.8%, 93.5%, 25.8%; Holter was 66.7%, 16.7% 81.5%, 16.6%. Of the four noninvasive rest tests, EM had the highest diagnostic index, followed by ECG.
