目的:探讨食管癌、贲门癌术后发生心律失常的危险因素。方法:对106例食管癌、贲门癌术后发生心律失常患者的临床资料进行多因素Logistic回归分析,判定年龄、术前心电图异常、术前有无合并症(高血压、冠心病、糖尿病、肺部疾患)、FEV1/FVC%、MVV%、术前血钾、手术方式、手术时间等因素与术后发生心律失常的相关强度,推测可能导致术后心律失常发生的危险因素。结果:患者术前合并高血压、冠心病、肺部疾患及术前心电图异常、FEV1/FVC%<70%、术前血钾<4.0 mmol/L 6个因素与术后心律失常发生有显著相关性。结论:术前积极治疗心肺部合并症、术前心电图异常者进行针对性处理及术后重点心电监护、术前改善低肺功能、术前适当补钾均可预防和减少术后心律失常的发生。 Objective: To explore the risk factors of cardiac arrhythmia after esophageal cancer and cardiac cancer. Methods: The clinical data of 106 patients with cardiac arrhythmia after esophageal cancer and cardia cancer were analyzed by multivariate logistic regression analysis to determine the age, preoperative electrocardiogram abnormalities, preoperative complications (hypertension, coronary heart disease, diabetes, lung And the related intensity of postoperative arrhythmia, presumed the risk factors of postoperative arrhythmia, such as FEV1 / FVC%, MVV%, preoperative serum potassium, operation method, operation time and other factors. Results: Preoperative hypertension, coronary heart disease, pulmonary disease and preoperative ECG abnormalities, FEV1 / FVC% <70%, preoperative serum potassium <4.0 mmol / L 6 factors were significantly associated with postoperative arrhythmia Sex. Conclusion: Preoperative positive treatment of cardiopulmonary complications, preoperative ECG abnormalities were targeted treatment and postoperative focus of ECG monitoring, preoperative improvement of low lung function, preoperative appropriate potassium can prevent and reduce postoperative arrhythmia occur.
