目的探讨静息心电图与冠状动脉造影对诊断冠心病的临床价值及其相关性。方法对 876例冠心病和可疑冠心病进行12导联静息心电图和冠状动脉造影检查 ,并对其结果进行对照性分析。结果心电图表现与冠状动脉病变一致者 5 65例( 64 5 % ) ,其中心电图呈心肌缺血性改变而冠状动脉有狭窄病变者 3 91例 ( 4 4 6% ) ,心电图和冠状动脉均正常者 174例( 19 9% )。心电图表现与冠状动脉病变不一致者 3 11例 ( 3 5 5 % ) ,其中心电图正常而冠状动脉狭窄者 166例 ( 18 9% ) ,心电图呈心肌缺血性改变而冠状动脉正常者 14 5例 ( 16 6% )。结论临床上不能单纯依靠心电图来诊断冠心病 ,要根据临床表现、心电图运动负荷试验、动静态心肌断层显像或冠状动脉造影等检查 ,综合判断 ,以明确诊断
Objective To investigate the clinical value of rest electrocardiogram and coronary angiography in the diagnosis of coronary heart disease and its correlation. Methods 8-lead coronary heart disease and suspected coronary heart disease by 12-lead resting ECG and coronary angiography, and the results of a controlled analysis. Results The electrocardiogram showed that 65 electrocardiograms (64 5%) were consistent with those of coronary artery. Electrocardiogram showed myocardial ischemic changes while 3 91 cases (446%) had coronary artery stenosis. Electrocardiogram and coronary artery were normal 174 cases (19 9%). There were 3,111 (35.5%) patients whose electrocardiogram was not in agreement with coronary artery disease. There were 166 cases (18.9%) with normal electrocardiogram and coronary artery stenosis, 156 cases with myocardial ischemic change and 156 cases with normal coronary artery 16 6%). Conclusion Clinicians can not simply rely on the ECG to diagnose coronary heart disease, according to clinical manifestations, ECG exercise stress test, dynamic and static myocardial imaging or coronary angiography and other tests, comprehensive judgment to confirm the diagnosis
