Postpneumonectomy electrocardiographic (ECG) changes have not been well-defined.
We reviewed the clinical data and the preoperative and postpneumonectomy ECGs of 15 patients who had pneumonectomy.
All postpneumonectomy ECGs showed a higher heart rate and two (13%) showed diffuse ST elevation. Four patients (27%) had transient atrial arrhythmias. Five patients (33%) had some ECG findings of acute cor pulmonale. A leftward shift of the QRS axis occurred after left pneumonectomy. The precordial transitional zone shifted counterclockwise after right pneumonectomy.
Except for one case of septal myocardial infarction, postpneumonectomy ECG changes appeared to result from the pneumonectomy and not from cardiopulmonary disease. Recognition of expected postpneumonectomy ECG findings will help avoid confusing these changes with acute cardiac and pulmonary events, which should reduce patient morbidity and costs.
肺切除术后心电图（ECG）变化尚未明确界定。
我们回顾了15例行肺切除术患者的临床资料以及术前和术后的心电图。
所有肺切除术后的心电图均显示心率加快，2例（13%）出现弥漫性ST段抬高。4例（27%）出现短暂性房性心律失常。5例（33%）有急性肺心病的一些心电图表现。左肺切除术后QRS电轴向左偏移。右肺切除术后心前区过渡区逆时针移位。
除1例间隔心肌梗死外，肺切除术后的心电图变化似乎是由肺切除术引起的，而非心肺疾病所致。认识到肺切除术后预期的心电图表现将有助于避免将这些变化与急性心脏和肺部事件相混淆，这应能降低患者的发病率和费用。
