肺癌肺切除术后心电图分析

Analysis of Postoperative Electrocardiogram of Patients with Lung Cancer

目的探讨肺癌患者肺切除术后心电图变化的特点及其病因。方法选择原发性肺癌患者92例，分两组进行检测分析。心包内肺切除组37例、常规肺切除组55例，于术前、术后进行心电图动态检测。结果心包内肺切除术后sT段抬高31例（83．8％），心律失常23例（62．2％），Q-T间期延长19例（51．4％），与常规肺切除比较，差异有统计学意义（P〈0．05）。常规肺切除术后ST段压低10例（18．2％），与心包内肺切除比较，差异有统计学意义（P〈0．05）。心包内肺切除术后T波改变26例（70．3％），常规肺切除28例（50．9％），两组比较差异无统计学意义。结论肺癌患者心包内肺切除术后心电图异常率明显增加，主要表现为心律失常、sT段抬高、Q—T间期延长。常规肺切除术后心电图异常主要表现为sT段压低。提示手术对肺癌患者术后心电图变化具有一定的影响。

Objective To explore the characteristics of postoperative electrocardiogram（ECG） of patients with lung cancer received pneumonectomy and its causes. Methods 92 patients with primary lung cancer were divided into two groups and given two different surgeries.ECG was monitored before and after the operation. 37 cases in the group A were given pneumonectomy in pericardium, and 55 cases in the group B were treated with routine pneumonectomy. Results There were 31 cases of ST increase （83.8%）, 23 cases of cardiac arrhythmia（62.2%） and 19 cases of Q-T interval changed（51.4%）, which had significant difference while compared with the group B （P〈0.05）. There were 10 cases with ST segment depressed （18.2%） in the group B, showing obvious difference with the group A（P〈0.05）. The change of T wave occurred in 26 cases（70.3%） in the group A and 28 cases（50.9%） in the group B respectively, without significant difference（P〉0.05）. Conclusion The abnormality of postoperative ECG increases apparently in patients with lung cancer who receive pneumonectomy in pericardium. The main manifestations include arrhythmia, ST segment increased, and Q-T interval prolonged. ST segment depressed is the main manifestation in patients received routine pneumonectomy. Operation has some influence on the change of postoperative ECG in patients with lung cancer.
