摘要
目的:探讨心电图运动实验(TET)对冠心病患者诊断的敏感性。方法:对133例胸痛患者进行 TET和冠状动脉造影(CAG)检查,对比TET和CAG的结果,计算TET的敏感性、特异性和准确性。结果: 此组患者TET诊断冠心病的敏感性为89．0％,特异性为55．0％,准确性为73．7％。结论:TET对于正确诊断冠心病、评价心肌缺血和药物及介入治疗后的效果有重要意义,但其敏感性及特异性有待于进一步提高。
Objective： To investigate the sensitivity of electrocardiogram treadmill exercise test （TET） for diagnosing coronary heart disease （CHD）. Methods ：133 patients with chest pain undergoing TET and coronary angiography （CAG） were enrolled. The results of TET and CAG were compared to evaluate the sensitivity,specificity and accuracy of TET. Results ： The sensitivity, specificity and accuracy of TET for diagnosing CHD was 89.0 %, 55.0 %, and 73.7 %. Conclusion： TET has significiance on diagnosing CHD, evaluating cardiac ischemia and effect of invention treatment,but its sensitivity and specifictiy should be improved.
