本文对单例心肌梗塞患者的心电图作为左室收缩功能的定量预测指标进行了研究。通过选择性左心室造影研究了进入高血压外科控制计划的前509名连续受试者。根据Minnesota Q-QS代码对受试者既往因急性心肌梗死住院期间采集的心电图进行分类。该研究表明，较低（即更显著）的Q-QS代码与左心室功能降低高度相关，这是通过射血分数降低和显示异常收缩运动的左心室节段数量增加来测量的。此外，节段性室壁运动异常的位置与心电图Q-QS代码的位置相关。
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.
