心房颤动是永久起搏器治疗后的常见并发症,起搏器不同工作模式可对房颤发生产生影响。心脏起搏改变了正常心脏激动顺序,使双房间、双室间及房室间激动不同步,带来不利的血流动力学效应,导致心房机械重构和电重构,这是房颤发生的主要机制。因此寻找更为生理的起搏模式,减少起搏治疗后房颤的发生成为该领域研究的热点。减少非必要的VVI,房间隔、Bachmann束或冠状窦口附近起搏,多部位心房起搏和具有特殊抗房颤程序的起搏器能够在一定程度上减少房颤发生,是优化起搏模式预防房颤的发展方向。
Atrial fibrillation is a common complication after permanent pacemaker treatment. Different working modes of pacemaker can influence the occurrence of atrial fibrillation. Cardiac pacing changes the normal cardiac activation sequence, causing asynchrony in double rooms, double rooms, and interventricular septum, resulting in adverse hemodynamic effects that lead to atrial mechanical remodeling and electrical remodeling, which is atrial fibrillation The main mechanism. Therefore, to find more physiological pacing mode and reduce the occurrence of atrial fibrillation after pacing therapy become the hotspot in this field. Reducing non-essential VVI, atrial septum, pacemaker near the Bachmann’s bundle or coronary sinus ostium, multi-location atrial pacing and pacemaker with special anti-atrial fibrillation procedures can reduce atrial fibrillation to a certain extent and optimize pacing mode Prevention of the development of atrial fibrillation.
