First-degree atrio-ventricular (AV) block is defined as a PR interval longer than 200 ms. If too long, it can become clinically relevant and may mimic a pacemaker syndrome. We report the case of a young woman with a long PR interval, probably congenital, with episodes of syncope and dizziness since childhood. Pseudo-pacemaker syndrome is rare and is a Class IIa recommendation for a pacemaker implantation. A dual-chamber pacemaker was implanted and short AV delay was programmed, with rapid clinical improvement.
一度房室（AV）阻滞定义为 PR 间期大于 200ms。如果太长，可能具有临床意义，并可能模拟起搏器综合征。我们报告了一例年轻女性，其 PR 间期较长，可能为先天性，自幼出现晕厥和头晕。假性起搏器综合征罕见，是起搏器植入的 IIa 类适应证。植入双腔起搏器并程控短 AV 延迟，患者快速临床改善。
