AAI pacing offers better hemodynamic characteristics than dual-chamber pacing and is the optimal mode for patients with sick sinus syndrome without AV conduction disorders. AAI pacing may be achieved by single-chamber atrial pacing, by programming a dual-chamber pacemaker to the AAI mode, or by programming a dual-chamber pacemaker to DDD mode with a long AV delay. The annual incidence of AV block development in patients with sick sinus syndrome is low, probably 1-5%, but there is no method of detecting patients immune or prone to future development of AV block. Chronotropic incompetence is often present in patients with sick sinus syndrome but the value of additional rate response is not yet firmly established. Our recommendations for the choice of the optimal method of pacing are discussed.
AAI起搏比双腔起搏具有更好的血流动力学特征，是无房室传导障碍的病态窦房结综合征患者的最佳起搏模式。AAI起搏可通过单腔心房起搏、将双腔起搏器程控为AAI模式或通过将双腔起搏器程控为具有较长房室延迟的DDD模式来实现。病态窦房结综合征患者发生房室传导阻滞的年发生率较低，可能为1% - 5%，但尚无检测对未来发生房室传导阻滞有免疫或易感性患者的方法。变时性功能不全在病态窦房结综合征患者中常存在，但额外频率应答的价值尚未完全确立。本文讨论了我们对选择最佳起搏方法的建议。
