Four hundred and ninety-two patients with coronary artery disease underwent analysis of their electrocardiograms, coronary arteriograms, and ventriculograms. Significant Q-waves were correlated with critical coronary occlusions (greater than or equal 75 per cent obstruction) and ventricular contractility. It was found that Q-waves correlate equally well with ventriculographic abnormalities and critical coronary occlusions. The Q-wave correlation varied from 77 to 87 per cent, depending on the area of myocardium under consideration, except for true posterior myocardial infarction, which correlated 55 per cent with ventriculographic abnormalities and 55 per cent with critical coronary occlusions. Significant Q-waves in Leads II, III, and aVF are better indicators of ventriculographic abnormality than in Leads III and aVF alone, whereas Q-waves in the latter two leads are more definitive than in Lead III alone. Patients who have critical coronary occlusions and normal electrocardiograms have normal ventriculograms in 71 to 78 per cent of the cases, again depending on the area of the myocardium under consideration. Thus, the normal electrocardiogram correlates better with the ventriculogram than with coronary pathology. The abnormal electrocardiogram correlates equally well with both.
492例冠心病患者接受了心电图、冠状动脉造影和心室造影分析。显著Q波与严重冠状动脉闭塞（阻塞程度大于或等于75%）及心室收缩性相关。研究发现，Q波与心室造影异常及严重冠状动脉闭塞的相关性同样良好。Q波相关性在77%至87%之间，取决于所考虑的心肌区域，但真正的后壁心肌梗死除外，其与心室造影异常的相关性为55%，与严重冠状动脉闭塞的相关性为55%。与单独的Ⅲ导联和aVF导联相比，Ⅱ、Ⅲ和aVF导联出现显著Q波是心室造影异常更好的指标，而后两个导联中的Q波比单独的Ⅲ导联更具决定性。有严重冠状动脉闭塞且心电图正常的患者，71%至78%的病例心室造影正常，同样取决于所考虑的心肌区域。因此，正常心电图与心室造影的相关性优于与冠状动脉病变的相关性。异常心电图与两者的相关性同样良好。
