目的 探讨有适应证的阵发性心房颤动(房颤)患者永久性房间隔起搏的可行性和安全性。方法 先行心内电生理标测,寻找使双心房同步激动的房间隔最佳起搏点,采用主动固定方法将导线固定于该部位。结果 18例伴有房间传导阻滞的阵发性房颤患者,14例患者完成房间隔标测和永久性起搏导线植入手术,4例未能成功植入房间隔起搏导线。结论 在伴有房间传导阻滞的阵发性房颤患者中永久性房间隔起搏是安全可行的。
Objective To investigate the feasibility and safety of permanent atrial septal pacing in patients with paroxysmal atrial fibrillation (AF). Methods First electrophysiological mapping of the heart to find the best atrial septum atrial pacemaker synchronization, the use of active fixation method to the wire fixed in the site. Results Eighteen patients with paroxysmal atrial fibrillation with conduction block in the room and 14 patients underwent atrial septal mapping and permanent pacing lead implantation. Four patients failed to successfully implant atrial septal pacing lead. Conclusion Permanent atrial septal pacing in patients with paroxysmal atrial fibrillation associated with room conduction block is safe and feasible.
