Long-term ECG recording on tape (LTER) was performed in 32 consecutive patients undergoing cholecystectomy. Twenty-two of the patients recorded showed ST-segment changes during the per- and early post-operative period. ST-segment depression was the most common change seen in 17 patients; however, 12 patients showed ST-segment elevation. In only nine patients were the ST-segment changes seen to be associated with major changes in pulse or blood pressure. ST-segment changes were seen as frequently in patients with, as without, known cardiovascular disease. All patients had an uncomplicated postoperative course and no case of myocardial infarction was seen. ST-segment changes during elective surgery seem to be a common phenomenon. The etiology of the observed changes is not clear and its value in the detection of per- or postoperative myocardial ischemia needs to be further evaluated.
对32例连续接受胆囊切除术的患者进行了磁带式长期心电图记录（LTER）。记录的患者中有22例在手术期间及术后早期出现ST段改变。ST段压低是17例患者中最常见的改变；然而，12例患者出现ST段抬高。仅9例患者的ST段改变与脉搏或血压的重大变化相关。有已知心血管疾病的患者和无已知心血管疾病的患者出现ST段改变的频率相同。所有患者术后病程均无并发症，未出现心肌梗死病例。择期手术期间的ST段改变似乎是一种常见现象。观察到的改变的病因尚不清楚，其在检测围手术期或术后心肌缺血中的价值需要进一步评估。
