目的 探讨肿瘤开胸术后心脏病的发生、原因及心电监护的意义.方法111例肿瘤开胸术后患者,于监护室内行连续心电监护,持续3～5天.结果 肿瘤开胸术后心脏病的发生率较高,占16.22%.其发生率与年龄、既往心脏病史、手术操作、疼痛有关.结论 加强术后连续心电监护及采取积极有效防治措施对减少术后心脏病的发生,提高围手术期安全性具有重大意义. Objective To investigate the occurrence and causes of cardiac diseases after electroplating and the significance of electrocardiographic monitoring. Methods 111 patients undergoing thoracotomy were subjected to continuous electrocardiographic monitoring in the monitoring room for 3 to 5 days. The incidence of post-cardiac disease was high, accounting for 16.22%. The incidence was related to age, history of previous heart disease, surgical operation, and pain.
