【摘要】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,28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。27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。 【关键词】肺切除 心包 心电图

【Abstract】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. 【Key words】Pneumonectomy Pericardium Electrocardiogram
ST段抬高常见于急性心肌梗塞、变异型心绞痛、急性心包炎、早期复极综合征、高钾血症等疾病。而肺叶或全肺切除手术对ST-T的影响,目前报告较少。我们对57例病人进行术后心电图动态监测,以观察术后ST-T改变的特点,分析其影响因素,为临床诊断和治疗,特别是术后急性心梗的鉴别诊断提供依据。
资料与方法
一、对象 1.对照组:原发性肺癌行肺叶或全肺切除患者27例,男性22例,女性5例,余详见表1。 2.观察组:原发性肺癌行肺叶或全肺切除,同时行部分心包切除或有心包外损伤(指心包外处理肺血管时伤及心包)患者30例,男性28例,女性2例,余详见表1。 两组在年龄上无显著性差异(P>0.05)。 二、仪器 日本福田FX-1301型心电图机。
