摘要 对8例陈旧性心肌梗死(OMI)患者于冠状动脉旁路移植术(CABG)前、后分别检测信号平均心电图(SA-ECG)，观察CABG后，即晚期再灌注对心室晚电位(VLP)的影响。发现CABG后滤波后QRS波群时限明显缩短(95.0±10.2 ms vs 105.0±16.7 ms,P<0.05)。8例中3例VLP阳性，CABG后1例VLP转为阴性。提示晚期再灌注可能对改善冠心病患者预后有一定作用。

Abstract Signal-averaged electrocardiogram (SA-ECG) was performed before and after coronary artery bypass grafting (CABG) in 8 patients with prior myocardial infarction.The purpose of this study was to observe effect of CABG on ventricular late potentials (VLP).Results:CABG improved SA-ECG variables,FQRS shortened significantly (95.0±10.2 ms vs 105.0±16.7 ms,P<0.05).1 of 3 patients with VLP lost their VLP after CABG.These findings suggest that late reperfusion might improve the prognosis of patients with coronary artery disease.
