目的探讨动态心电图与平板运动实验对冠心病的诊断价值。方法选择36例可疑冠心病患者,分组进行24h动态心电图与平板运动试验检查,以冠脉造影结果做对比,比较两种方法对冠心病心肌缺血阳性检出率,诊断冠心病心肌缺血的特异性。结果动态心电图检出冠脉病变的敏感性为77.8%,运动平板敏感性69.4%,差异有统计学意义。结论动态心电图与平板运动试验均可作为无创诊断冠心病的有效方法。
Objective To investigate the diagnostic value of ambulatory electrocardiogram and treadmill exercise test on coronary heart disease. Methods Thirty-six patients with suspected coronary heart disease were selected and examined by 24-hour electrocardiogram and treadmill exercise test. The coronary angiography results were compared with each other. The positive rate of myocardial ischemia was compared between the two methods, and the diagnosis of myocardial ischemia in patients with coronary heart disease Specificity. Results The sensitivity of dynamic electrocardiogram in detecting coronary artery lesions was 77.8%, motor sensitivity of plate was 69.4%, the difference was statistically significant. Conclusion Holter and treadmill exercise tests can be used as an effective noninvasive method to diagnose coronary heart disease.
