摘要
目的:通过冠脉造影探讨心电图对冠心病的诊断价值。方法:对226例可疑冠心病患者进行心电图与冠脉造影进行对比分析。结果:心电图诊断冠心病的灵敏度为86.49%,特异度为65.38%,假阳性率为34.62%,假阴性率为13.51%。心电图随着冠状动脉病变支数增加而检出冠心病的阳性率增高。结论:心电图是临床诊断冠心病最快捷、简便、经济而无创的有效方法,但仍存在一定的局限性。
Objective: To evaluate the role of the normal electrocardiogram(ECG)in diagnosing coronary heart disease(CHD) by coronary angiography(CAG). Methods: 226 patients with doubtful CHD were examined by ECG and CAG. Results: The sensitivity of ECG was 86.49%, the specificity was 65.38%, the false positive rate was 34.62% and the false negative rate was 13.510%. The detection rate of CHD by ECG increased according to the number of VeSSel disease in CHD. Conclusion: ECG is the clinical diagnosis of coronary heart disease are the most efficient, simple, economical and wayof Non invasive, but there are still some limitations.
