研究目的:

通过前瞻性、随机对照研究,明确应用低强度迷走神经刺激是否可以预防术后的房颤发生。  

Objectives of Study:

To observe whether calcium autonomic denervation prevents postoperative atrial fibrillation.

药物成份或治疗方案详述:

开始常规心脏搭桥手术,手术结束后,将双极线缝在上腔静脉旁迷走神经神经节前纤维上。术中进行刺激强度测试,明确减慢心率的强度阈值,在LSS组中,手术结束后以高频率(20Hz)刺激低强度(低于减慢心律阈值50%)刺激72h。在对照组中,不进行刺激。 

Description for medicine or protocol of treatment in detail:

After the operation, the bipolar suture was sutured on the preganglionic fiber of the vagus nerve adjacent to the superior vena cava. Intraoperative stimulation intensity test was performed to clarify the intensity threshold for slowing the heart rate. In the LSS group, high frequency (20Hz) stimulation with low intensity (below 50% of the threshold for slowing heart rhythm) was stimulated for 72 hours after the operation. In the control group, no stimulation was performed.
