高频心电图与核素心肌断层显像对冠心病诊断价值的比较

THE COMPARISION ON THE VALUE OF HFECG AND SPECT TO DIAGNOSE CAD

以￣（９９ｍ）锝一ＭＩＢＩ核素心肌断层显像（ＳＰＥＣＴ）为参照标准，在１２６例检测对象中评价了高频心电图（ＨＦＥＣＧ）对冠心病（ＣＡＤ）的诊断价值。结果显示在患病率为６１．９０％的情况下，ＨＦＥＣＧ诊断ＣＡＤ的敏感性和特异性分别为８８．１％和７６．６％；阳性预测值和阴性预测值分别为８５．９％和７９．９％。结果表明，ＨＦＥＣＧ是一种较理想的ＣＡＤ辅助检测手段。

We have evaluated the diagnosis value of HFECG for CAD in 126 subjectsconsidering 99m Tc-MIBI SPECT as the standard.The results show that HFECG has asensitivity(88.1%),and a specificity(76.6%)in diagnosis of CAD when morbidity rate(61. 9%),petive expectancy value is 85.9%,negative expectancy value is 79.90%. Theconcltlsion is that HFECG is a more ideal assistant way in diagnosis of CAD.
