Atrioventricular junction (AVJ) ablation is an effective therapy in patients with symptomatic atrial fibrillation who are intolerant to or unsuccessfully managed with rhythm control or medical rate control strategies. A drawback is that the procedure mandates a pacing system. Overall, the safety and efficacy of AVJ ablation is high with a majority of the patients reporting significant improvement in symptoms and quality-of-life measures. Risk of sudden cardiac death after device implantation is low, especially with an appropriate postprocedure pacing rate. Mortality benefit with AVJ ablation has been shown in patients with heart failure and cardiac resynchronization therapy devices.
房室交界区（AVJ）消融术对于有症状的心房颤动患者是一种有效的治疗方法，这些患者不能耐受节律控制或药物心率控制策略，或采用这些策略治疗失败。一个缺点是该手术需要植入起搏系统。总体而言，AVJ消融术的安全性和有效性较高，大多数患者报告症状和生活质量指标有显著改善。植入装置后心脏性猝死的风险较低，尤其是术后起搏频率适宜时。在心力衰竭患者和心脏再同步治疗装置植入患者中，已显示AVJ消融术具有降低死亡率的益处。
