The electrocardiogram as a quantitative predictor of left ventricular systolic function was investigated in subjects with one myocardial infarction. The first 509 consecutive subjects to enter the Program of Surgical Control of Hyperlipidemia were studied by selective left ventriculography. Electrocardiograms taken during a prior hospitalization of the subjects for acute myocardial infarction were classified according to the Minnesota Q-QS codes. This study showed that the lower (ie, the more significant) Q-QS codes were highly correlated with reduced left ventricular function as measured both by a lower ejection fraction and by a greater number of left ventricular segments showing abnormal systolic motion. In addition, the location of segmental wall motion abnormalities correlated with the electrocardiographic site of the Q-QS code.
在患有一次心肌梗死的受试者中，研究了心电图作为左心室收缩功能定量预测指标的情况。对首批连续进入高脂血症外科治疗项目的509名受试者进行了选择性左心室造影研究。根据明尼苏达Q-QS编码，对受试者先前因急性心肌梗死住院期间所做的心电图进行分类。这项研究表明，较低（即更显著）的Q-QS编码与左心室功能降低高度相关，左心室功能降低通过较低的射血分数和较多显示收缩运动异常的左心室节段数量来衡量。此外，节段性室壁运动异常的位置与Q-QS编码的心电图部位相关。
