We introduced a simple technique to eliminate electromagnetic interference between a left ventricular assist device (LVAD) and an implantable cardioverter defibrillator (ICD). A 43-year-old male with heart failure and a reduced ejection fraction who had an ICD presented with decompensated heart failure and received an LVAD as a bridge to transplant. Remote monitoring showed persistent atrial fibrillation causing an inappropriate ICD shock leading to a decision to disable shock therapies. However, an in-office interrogation was unsuccessful due to electromagnetic interference. Patient was instructed to extend his arm above his head on the ipsilateral side of the ICD, thus increasing the distance between LVAD and ICD, eliminating the interaction to allow reprogramming of the device.
我们介绍了一种简单的技术，以消除左心室辅助装置（LVAD）和植入式心脏复律除颤器（ICD）之间的电磁干扰。一名 43 岁男性患有心力衰竭和射血分数降低，他装有 ICD，因心力衰竭失代偿而接受 LVAD 作为移植桥。远程监测显示持续性心房颤动导致 ICD 不适当电击，导致决定禁用电击疗法。然而，由于电磁干扰，在办公室进行的询问未能成功。患者被指示将手臂伸到 ICD 的同侧上方，从而增加 LVAD 和 ICD 之间的距离，消除相互作用，以便重新编程设备。
