In patients with frequent right ventricular stimulation, worsening of heart failure and atrial fibrillation may occur. Avoidance of unnecessary right ventricular pacing is a major requirement for pacemaker selection and programming in patients with sinus node disease or intermittent AV block. In dual chamber pacemakers this goal can be achieved by programming a long AV delay or an AV delay hysteresis. Algorithms that allow AAI pacing in a dual chamber pacing mode and change to DDD mode in case of high degree AV block are a new attempt to avoid unnecessary right ventricular pacing. The article describes various strategies to avoid unnecessary ventricular pacing and discusses their advantages and disadvantages.
在频繁进行右心室刺激的患者中，可能会出现心力衰竭和心房颤动加重的情况。对于患有窦房结疾病或间歇性房室传导阻滞的患者，避免不必要的右心室起搏是起搏器选择和程控的主要要求。在双腔起搏器中，可通过设置较长的房室延迟或房室延迟滞后实现这一目标。允许在双腔起搏模式下进行AAI起搏并在发生高度房室传导阻滞时转换为DDD模式的算法是避免不必要右心室起搏的新尝试。本文介绍了避免不必要心室起搏的各种策略，并讨论了它们的优缺点。
