心房颤动(房颤)是永久型起搏器植入患者最容易发生的快速性心律失常,也是心动过缓症状改善后的主要发病原因,而大部分患者在房颤发作时没有症状。目前,在这些安装起搏器的患者中减少房颤发生的有效策略是设置最小化心室起搏模式,以避免因右室心尖起搏引起的双室收缩不同步,而后 Atrial fibrillation (atrial fibrillation) is the most likely cause of tachyarrhythmia in patients with permanent pacemaker implants, and is also the leading cause of post-bradycardiac symptoms. Most patients have no symptoms at onset of atrial fibrillation. Currently, an effective strategy to reduce the occurrence of atrial fibrillation in these pacemaker-mounted patients is to set the minimization of ventricular pacing mode to avoid dyssynchrony of binocular contraction due to RV apical pacing
