肺癌患者肺切除术后ST-T改变的临床探讨

A discussion on ST-T changes caused by pneumonectomy in patients with lung cancer

目的 探讨肺癌患者行肺切除术后 ST- T改变的特点及机制。方法 对 57例肺癌行肺切除术患者于术前、术后行心电图检测。结果 30例肺切除同时行心包部分切除或有心包外损伤的患者中 ,2 8例 (93.3% )术后 ST段较术前呈水平或上凹形抬高。术后 1～ 2周恢复至术前水平 ,不伴 QRS改变。 2 7例单纯肺切除患者术后未见 ST段改变。结论 肺癌手术伤及心包时可引起 ST- T改变。

Objective To explore the characteristics and mechanisms of ST T changes caused by pneumonectomy in patients with lung cancer.Methods The electrocardiogram of 57 patients with lung cancer were evaluated before and after pneumonectomy.Results There were 28 of 30 patients (93.3%) who underwent pneumonectomy and pericardiotomy or pericardium injury with ST segments shifted up horizontally or hollowly.These changes recovered after 1～2 weeks of pneumonectomy without QRS changes.There were no ST changes in 27 patients who had simple pneumonectomy.Conclusions The changes of ST T are related with the injured pericardium in pneumonectomy patients.
