多巴酚丁胺心电图试验和心电图运动试验诊断冠心病的对照分析

Comparison of dobutamine electrocardiography testingand treadmill exercise testing indiagnosing coronary heart disease

２７例临床拟诊冠心病（ＣＨＤ）患者在冠状动脉造影前同期作多巴酚丁胺心电图试验（ＤＥＴ）和心电图平板运动试验（ＴＥＴ）。两种试验的敏感度、特异度和准确度分别为８６％与８６％，７７％与８５％，８２％与８５％，符合率为８１％。统计学处理结果证明两种方法诊断ＣＨＤ效果相同。１１例同为阳性患者的心电图中，ＳＴ段改变的形式、程度及导联基本相同。研究表明，对因各种原因不能作ＴＥＴ的患者，可用ＤＥＴ替代。

Twenty-seven patients diagnosed coronary heart disease (CHD) were performeddobutamine electrocardiography testing (DET) and treadmill exercise testing (TET) before coro-nary angiography. The sensitivity, specifity and accuracy in both testing were 86% and 86%,77% and 80% , 82% and 85% to diagnose CHD, respectively. The results suggested that theefficacy of both testing was same to diagnose CHD , and there was no difference in form or degreeor site of positive change with respect to ST segment in both testing. The DET is a possible alter-native to TET when TET can not be performed.
