目的探讨肺切除患者术后发生心律失常的情况其与年龄、术前肺功能、切除范围、术后肺部并发症的关系。方法对行肺切除治疗肺癌的236例患者作回顾性总结。结果肺切除术后心律失常发生率为10.60%,且年龄>70岁、肺切除范围、术前肺功能与术后患者发生心律失常相关。结论肺切除术后患者心律失常发生率增加,心房纤颤是最常见的心律失常。 Objective To investigate the incidence of postoperative arrhythmia in patients with pulmonary resection and its relationship with age, preoperative pulmonary function, resection scope and postoperative pulmonary complications. Methods A total of 236 patients undergoing lung resection for lung cancer were retrospectively reviewed. Results The incidence of arrhythmia after pneumonectomy was 10.60%, and the age was> 70 years. The range of lung resection and preoperative pulmonary function were related to arrhythmia in patients after operation. Conclusion The incidence of arrhythmia in patients after pneumonectomy increased, atrial fibrillation is the most common arrhythmia.
