肺癌肺切除术后心电图分析

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(P0.05)。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(P0.05)。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。

Analysis of postoperative electrocardiogram of patients with lung cancer

Objective To explore the characteristics of postoperative electrocardiogram （ECG） of patients with lung cancer re- ceived pneumonectomy and its causes. Methods 92 patients with primary lung cancer were divided into two groups and given two differ- ent 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 eases 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 〈 O. 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 re- spectively, 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 in- fluence on the change of postoperative ECG in patients with lung cancer.
