A 26-year-old patient with prior surgery for Ebstein's anomaly and a pacemaker (placed for post-surgical heart block and poor underlying rhythm) underwent SICD was placement. During defibrillation testing, device-device interaction led to undersensing of ventricular fibrillation with failure to shock. Increasing the pacemaker sensitivity resolved the problem but post shock pacing was unable to capture the heart after both shocks. The patient underwent removal of both the pacemaker and the SICD and placement of a transvenous ICD. Complex device-device interactions can occur in patients who are pacemaker dependent and undergo placement of a SICD.
一位 26 岁的患者曾因 Ebstein 畸形和起搏器(用于术后心脏传导阻滞和基础节律不良)接受过手术,现进行可植入式除颤器(SICD)植入。在除颤测试期间,设备-设备相互作用导致心室颤动感知不足,未能电击。增加起搏器灵敏度解决了问题,但电击后起搏均无法捕获心脏。该患者接受了起搏器和 SICD 的移除,并植入了经静脉 ICD。对依赖起搏器并接受 SICD 植入的患者,可能会发生复杂的设备-设备相互作用。
