心房颤动是心脏术后最常见的并发症之一。随着近年来心脏外科手术患者的高龄化及危险因素的增高,术后心房颤动的发生率在上升,据报道心房颤动发生率在冠状动脉旁路移植术后可高达30%,冠状动脉旁路移植联合瓣膜术为60%。心房颤动的发生通常会延长住院时间,并有发生栓塞的危险。因此有必要对这一围手术期的并发症给予更多的关注,了解其发生机制、危险因素及预防措施,以减少此并发症的发生。 Atrial fibrillation is one of the most common complications after cardiac surgery. The incidence of postoperative atrial fibrillation has risen with an increase in age and risk factors for cardiac surgery in recent years. The incidence of atrial fibrillation has been reported to be as high as 30% after coronary artery bypass grafting. Coronary artery bypass Transplantation combined valve surgery was 60%. The occurrence of atrial fibrillation usually prolongs hospital stays and presents with the risk of embolism. Therefore, it is necessary to pay more attention to this perioperative complications, to understand its mechanism, risk factors and preventive measures to reduce the occurrence of this complication.
