摘　　要：随着心脏起搏技术的发展和进步,大量症状性心动过缓和完全性心脏传导阻滞的患者得到治疗。然而,起搏器置入患者仍需在随访中对起搏器参数设置进行不断优化,在获得最佳临床效果的同时,使得潜在的不利影响最小化。在起搏器的相关参数中,房室间期(AVdelay/AV interval,AVD/AVI)可以通过影响心室的前负荷影响心脏的射血能力,对于实现血流动力学方面的房室机械同步、避免电生理不利影响等方面有重要意义。既往对于起搏器优化的研究多集中于心脏再同步化治疗的患者,而对双腔起搏器人群涉及较少。本文拟就双腔起搏器AVD优化的目的、临床研究进展、起搏器的人工优化方法等作一综述。With the development and progress of cardiac pacing technology,a large number of patients with symptomatic bradycardia and complete heart block have been treated.However,patients with pacemaker implantation still need to optimize the pacemaker parameters in the follow-up,in order to obtain the best clinical effect and minimize the potential adverse effects.Among the parameters of dual chamber pacemaker,AV delay/AV interval(AVD/AVI)can affect the cardiac ejection capacity by affecting ventricular preload,which is of great significance for achieving atrioventricular synchronization and avoiding adverse effects of electrophysiology.Previous studies on pacemaker optimization mainly focused on patients with cardiac resynchronization therapy,but less on dual chamber pacemakers.In this paper,the purpose of AVD optimization,clinical research progress and artificial optimization methods of dual chamber pacemaker are reviewed.
