摘　　要：目的:探讨冠脉旁路移植术(CABG)后心电图出现异常Q波的临床意义,并评价其是否可作为CABG术后发生心肌梗死的诊断指标。方法:回顾性分析CABG术后心电图出现异常Q波15例患者手术前后超声心动图射血分数值、室壁运动情况,术后心肌酶、血流动力学情况和相关并发症等情况,并选CABG术后心电图无异常Q波的15例患者为对照组,对两组资料进行统计学分析。结果:两组以上观察指标的数值中无显著性差别(P均>0.05)。结论:冠脉旁路移植术后心电图出现异常Q波并非围术期心肌梗死和心肌缺血的特异性诊断指标,也不能做为术后早期测预后的指标。Objective：To investigate the clinical significance of abnormal Q wave in electrocardiogram（ECG） after coronary artery bypass graft（CABG）.Methods：A total of 15 aged patients who presented abnormal Q wave in ECG after CABG were included in the study.Ejection fraction value in ultrasonic cardiogram,regional wall motion abnormalities,myocardial enzyme value,hemodynamic abnormalities and relative complications before and after operation were recorded and retrospectively analyzed in these patients.Another 15 aged patients without abnormal Q wave in ECG after CABG were enrolled for control group.Statistical analysis was performed between the two groups.Results：There were no significant difference between the two groups in above indexes（P〉0.05 all）.Conclusion：Abnormal Q wave in ECG after CABG could not be used as either a specific diagnostic index for perioperative myocardial infarction and myocardial ischemia or an index indicated early prognosis after operation.
