A 74-year-old man experienced complete atrioventricular (AV) block 2 days after catheter ablation for right atrial (RA) macroreentrant tachycardia. We performed DDD pacemaker implantation with atrial septal pacing because other sites of pacing threshold were not acceptable. The maximum left ventricular outflow tract velocity time integral was 15.8 cm with sensed AV delay (40 ms) and 15.0 cm with paced AV delay (220 ms); however, this exceeded the pacemaker's maximum difference of 100 ms. We herein report the case of a large discrepancy in optimal AV delay intervals between sensed and paced atrial events, requiring consideration of proper pacemaker settings.

起搏器患者感知和起搏心房事件之间的最佳房室延迟存在很大差异

一名 74 岁男性因右心房 (RA) 大折返性心动过速导管消融 2 天后出现完全房室 (AV) 传导阻滞。我们进行了 DDD 起搏器植入和房间隔起搏,因为其他部位的起搏阈值是不可接受的。最大左心室流出道速度时间积分为 15.8 cm,有感知的 AV 延迟(40 ms)和 15.0 cm,有起搏的 AV 延迟(220 ms);但是,这超过了起搏器的最大差异 100 毫秒。我们在此报告感测和起搏心房事件之间的最佳 AV 延迟间隔存在较大差异的情况,需要考虑适当的起搏器设置。
