目的 探讨肺癌病人术后心律失常的原因。方法 观察肺癌病人术前、术后心电图改变,对某些心电图异常病人行术前准备。结果 324例肺癌病人术前心电图异常者155例占47.8％,术后出现心律失常者18.2％,多发生在术后24～48小时。结论 肺癌病人术后心律失常的原因多为心、肺功能储备不足,手术创伤及术后疼痛。对某些心电图异常者,术前药物治疗或高位硬膜外阻滞可有效预防术后心律失常的发生。
Objective To investigate the causes of postoperative arrhythmia in lung cancer patients. Methods The preoperative and postoperative electrocardiogram changes were observed in patients with lung cancer. Preoperative preparation was performed for some patients with abnormal electrocardiogram. Results Among the 324 patients with lung cancer, 155 had abnormal electrocardiogram before surgery and 47.8% of them had an arrhythmia after surgery. The occurrence of postoperative arrhythmia occurred in 18.2% of the patients, which occurred in 24 to 48 hours after surgery. Conclusion The main causes of postoperative arrhythmia in lung cancer patients are lack of heart and lung function reserve, surgical trauma and postoperative pain. For some abnormal electrocardiograms, preoperative drug therapy or high epidural block can effectively prevent the occurrence of postoperative arrhythmia.
