Left ventricular assist devices (LVADs) may induce electromagnetic interference (EMI) affecting implanted cardiac devices, including more novel subcutaneous implantable cardiac defibrillators (S-ICDs).
In this case series, the authors retrospectively reviewed courses of 6 patients with S-ICDs who underwent LVAD implantation at a single center.
Of the 6 patients reviewed, 4 experienced inappropriate ICD shocks, of which 3 resulted from EMI. Five of the 6 patients ultimately had S-ICD therapies disabled.
Due to EMI resulting in inappropriate shocks and improved tolerability of malignant arrhythmias, deactivation or removal of S-ICDs should be considered in patients undergoing LVAD implantation.
左心室辅助装置（LVAD）可能会诱发电磁干扰（EMI），影响植入式心脏装置，包括更新型的皮下植入式心脏除颤器（S-ICD）。
在这个病例系列中，作者回顾性分析了在单一中心接受LVAD植入的6例S-ICD患者的病程。
在回顾的6例患者中，4例经历了不适当的ICD电击，其中3例是由EMI引起的。6例患者中有5例最终停用了S-ICD治疗。
由于EMI导致不适当的电击以及恶性心律失常耐受性的提高，对于接受LVAD植入的患者，应考虑停用或移除S-ICD。
