ABSTRACT

[Objective] To re-evaluate the diagnostic value of electrocardiogram (ECG) for coronary heart disease (CHD) by coronary arteriogram (CAG). [Methods] ECG and CAG in 375 cases preliminarily diagnosed as having CHD were analyzed. [Results] ECG was abnormal in 252 cases and normal in 123 cases; 278 cases were diagnosed as having CHD and 97 non-CHD by CAG. CHD was confirmed in 205 cases from 252 with abnormal ECG and in 73 cases from 123 with normal ECG. The sensitivity of ECG for CHD was 73.7% and the specificity was 51.5% , indicating that the changes of ECG having different diagnostic value for CHD (P
