In this series of 198 patients studied prospectively before major noncardiac surgery, we previously reported that an abnormal preoperative electrocardiogram was a statistically significant independent predictor of an increased risk of postoperative complications, i.e., death, myocardial infarction, or myocardial ischemia. We therefore carried out a detailed analysis of the preoperative electrocardiographic (ECG) findings using Minnesota code criteria. Both ST-T abnormalities and intraventricular conduction delays showed a statistical trend toward a higher frequency in patients with a complicated vs. an uncomplicated postoperative course (82% vs. 59% and 24% vs. 7%, respectively). Although only a minority of patients with either ECG finding actually developed a complication (22% and 40% respectively), the preoperative ECG appears to be a useful screening method, with ST-T abnormalities and intraventricular conduction delays identifying patients at increased risk for postoperative complications.
在这组对198例拟行非心脏大手术患者进行前瞻性研究的病例中，我们之前报告过术前心电图异常是术后并发症（即死亡、心肌梗死或心肌缺血）风险增加的一个具有统计学意义的独立预测因素。因此，我们使用明尼苏达编码标准对术前心电图（ECG）结果进行了详细分析。ST-T异常和室内传导延迟在术后病程复杂与不复杂的患者中均呈现出频率更高的统计学趋势（分别为82%对59%和24%对7%）。尽管仅有少数有上述任一ECG表现的患者实际发生了并发症（分别为22%和40%），但术前ECG似乎是一种有用的筛查方法，ST-T异常和室内传导延迟可识别出术后并发症风险增加的患者。
