Fifty-five consecutive patients with a normal resting electrocardiogram and coronary artery disease were examined to determine left ventricular function. Fifty-two (95%) had no evidence of left ventricular asynergy; 3 patients had only mild hypokinesis. Of this group of patients, 25 (47%) had one vessel disease, 17 (30%) had two vessel disease, and 13 (23%) had three vessel disease. Significant left ventricular asynergy was not found in patients with coronary artery disease and normal electrocardiograms. In addition, a normal electrocardiogram was not related to the number of coronary arteries involved.
对55例静息心电图正常但患有冠状动脉疾病的患者进行检查以确定左心室功能。52例（95%）没有左心室协同失调的证据；3例仅有轻度运动减弱。在这组患者中，25例（47%）患有单支血管病变，17例（30%）患有双支血管病变，13例（23%）患有三支血管病变。在冠状动脉疾病且心电图正常的患者中未发现明显的左心室协同失调。此外，正常心电图与受累冠状动脉的数量无关。
