摘要
目的:评价动态心电图(DEC)诊断冠心病的价值。方法:拟诊冠心病患者78例,分别行冠状动脉造影术(CAG)和DEC检查,将两种检查结果对比分析。结果:78例患者中,DEC检查阳性45例,其中CAG阳性35例,阴性10例。DEC检查阴性33例,其中CAG阴性25例,阳性8例。DEC检出冠心病的敏感性为58.4%(35/60),特异性为44.4%(8/18),阳性预测值58.4%(35/60),阴性预测值44.4%(8/18),预测准确性为55.1%(43/78),假阳性率为55.5%(10/18),假阴性率为41.6%(25/60);冠状动脉单支病变较多支病变者易出现DEC假阴性。结论:DEC检查是冠心病诊断的一项筛选检查,与冠脉造影结合起来可以提高冠心病诊断的准确性。
Objective ：To evaluate the diagnostic value of coronary heart disease by using comparison of dynamic electrocardiogram with coronary angiography. Methods：78 patients with suspicious coronary heart disease were examined with treadmill exercise test and coronary angiography, the diagnostic results were compared and determined. Results：The results of treadmill exercise test were positive in 45 patients and coronary angiography were positive in 35 patients and negative in 9 patients. The results of treadmill exercise were negative in 33 patients and coronary anglography were negative in 25 patients of them and positive in 8 patients of them. The sensitivity, specificity, accuracy, false positive rate were 58.4% （35/60）,44.4% （8/18）,58.4% （35/60）,55.1% （43/78）,respectively. The dynamic electrocardiogram false negative rate of a single branch coronary artery was higher than that of multibranch coronary arteries. Conclusion：The dynamic electrocardiogram may be used as a screening test for diagnosis of coronary artery disease and the combination of dynamic electrocardiogram with coronary angiography can increase the diagnostic specificity and accuracy of coronary heart disease.
