动态心电图与平板运动试验诊断冠心病的价值分析

目的 探讨动态心电图检查与平板运动试验对冠心病的诊断价值.方法 对144例拟诊冠心病患者行动态心电图检查及平板运动试验,阳性患者行冠状动脉造影检查,根据冠状动脉检查结果进行比较分析.结果 次极量平板运动试验敏感性93.3%,特异性72.2%,预测准确性73.8%;动态心电图检出冠心病心肌缺血敏感性76.7%,特异性88.4%,阳性预测准确性57.1%.结论 平板运动试验和动态心电图联合检查可初步估测冠状动脉狭窄部位,对无条件行冠状动脉造影者,此两项检查可以提高心肌缺血阳性率的可靠性,以对提高冠状动脉病变部位的诊断水平.

Correlation analysis associated with Holter electrocardiogram and treadmill exercise test in diagnosis of coronary artery disease

Objective To investigate the diagnostic value of treadmill exercise tests (TET), Hoher electro-cardiogram in coronary artery disease(CAD) patients. Methods 144 patients who clinically diagnosed as CAD,un-derwent TET and Hoher electrocardiogram. Then the patients with the positive results were examined by coronary arte-riography(CAG). According to the results of CAG the diagnostic value of TET and Hoher electrocardiogram was per-formed with comparative analysis. Results The sensitivity, specificity and evaluated accuracy rates of TET were 93.3% ,72. 2% and 73. 8% respectively. But the sensitivity,specificity and positive evaluated accuracy rates of Hol-ter electrocardiogram to examine myocardial iachemia were 76.7%, 88.4%, 57.1%. Conclusions The combined examination of TET and Holter electrocardiogram could preliminarily estimate the stenosis site of coronary artery. For the patients with unconditional GAG, those two examinations could increase the diagnostic reliability of positive rate of myocardial isehemia, and on this basis to enhance the diagnostic level of the stenosis site of coronary artery.
