We present two patients with fractures within the pace-sense circuit of their Medtronic Sprint Fidelis leads who received inappropriate shocks from their Medtronic defibrillators during device interrogation. This was not simply a coincidence, but due to electromagnetic interference induced within the Sprint Fidelis lead by the device programmer during two-way communication with the defibrillator. Our subsequent investigations have uncovered at least two other similar incidents in Canada. We have also discovered that the Medtronic 'Auto-resume' feature may leave future patients uniquely vulnerable to such inappropriate shocks in the future.
我们报告了两名患者，他们的美敦力Sprint Fidelis导线的起搏感知回路发生骨折，在设备问询期间，其美敦力除颤器发出了不适当的电击。这并非简单的巧合，而是由于设备编程器在与除颤器进行双向通信时，在Sprint Fidelis导线内感应出电磁干扰所致。我们随后的调查在加拿大又发现了至少两起类似事件。我们还发现，美敦力的“自动恢复”功能可能会使未来的患者在未来特别容易受到这种不适当电击的影响。
