摘要
目的通过24 h动态心电图与冠状动脉造影对比分析,评价24 h动态心电图诊断冠心病的价值。方法拟诊冠心病患者92例,分别行冠状动脉造影术和24 h动态心电图检查,将两种检查结果对比分析,并对其资料进行临床分析。结果92例患者中24 h动态心电图检查阳性66例,其中冠状动脉造影阳性53例,冠状动脉造影阴性13例。24 h动态心电图检查阴性26例,其中冠状动脉造影阴性20例,冠状动脉造影阳性6例。动态心电图检出冠心病的敏感性为72.6%(53/73),特异性为31.5%(6/19),阳性预测值72.6%(53/73),阴性预测值33.3%(6/19),预测准确性为79.3%(73/92),假阳性率为68.4%(13/19),假阴性率为27.4%(20/73);冠状动脉单支病变较多支病变者易出现动态心电图假阴性。结论动态心电图检查是冠心病诊断的一项筛选检查,与冠状动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 artery diseases by comparison of dynamic electro-cardiogram with coronary angiography. Methods 92 patients with suspected coronary artery diseases were examined with dynamic electrocardiogram and coronary angiography, the diagnostic results were compared and determined. Results The results of dynamic electrocardiogram were positive in 66 patients and coronary angiography were positive in 53 patients and negative in 13 patients. The results of dynamic electrocardiogram were negative in 26 patients and coronary angiography-were negative in 20 patients of them and positive in 6 patients of them. The sensitivity, specificity , accuracy, false positive rate were 72.6%（53/73）,31.5% （6/19） ,72.6% （53/73） , 68.4% （13/19）, 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 The dynamic electrocardiogram with coronary angiography can increase the diagnostic specificity and accuracy of coronary artery diseases.
