In 90 patients with typical angina pectoris, resting ECGs and cardiac catheterization findings were independently reviewed to determine whether ECG findings could be used to predict the extent of disease and the state of the left ventricular (LV) function. Thirty consecutive patients in each of three ECG groups were studied: group 1, normal ECG: group 2, ST-T abnormalities; and group 3, Q wave infarction pattern. Triple vessel disease was present in 30 percent, 40 percent, and 66 percent of patients in groups 1, 2, and 3, respectively. The ejection fraction (percent) (mean +/- SD) was 65 +/- 12, 64 +/- 11, and 51 +/- 16 in groups 1, 2, and 3, respectively. With increasing ECG abnormality (group 1 to group 3), there was a tendency to both more extensive coronary disease and greater depression of left ventricular function. However, the resting ECG appeared to correlate bettter with the state of the LV function than with the extent of the coronary artery disease.
对90例典型心绞痛患者的静息心电图和心脏导管检查结果进行独立评估，以确定心电图结果是否可用于预测疾病程度和左心室（LV）功能状态。对三个心电图组中的每组30例连续患者进行研究：第1组，心电图正常；第2组，ST-T异常；第3组，Q波梗死图形。第1、2、3组患者中分别有30%、40%和66%存在三支血管病变。第1、2、3组的射血分数（百分比）（均值±标准差）分别为65±12、64±11和51±16。随着心电图异常程度增加（从第1组到第3组），冠状动脉疾病更广泛且左心室功能抑制更严重的趋势愈发明显。然而，静息心电图似乎与左心室功能状态的相关性比与冠状动脉疾病程度的相关性更好。
