We report a fatal device-device interaction between a wearable automated defibrillator (WAD; LifeVest - LifeCor, Inc., Pittsburgh, PA, USA) and a unipolar pacemaker that occurred in an 18-year-old patient listed for cardiac transplantation due to his failing Fontan. The patient developed ventricular tachycardia that was initially detected by the WAD. However, large unipolar pacing artifacts and specific WAD arrhythmia detection algorithms caused the WAD to revert to nonrecognition of the arrhythmia, which lead to the patient's death. We identify likely causes of the failure and suggest methods of preventing such occurrences in the future.
我们报告了一例可穿戴式自动除颤器（WAD；LifeVest - LifeCor公司，美国宾夕法尼亚州匹兹堡）与单极起搏器之间发生的致命设备-设备相互作用，该事件发生在一名18岁因功能性Fontan手术失败而等待心脏移植的患者身上。患者出现室性心动过速，最初由WAD检测到。然而，大的单极起搏伪迹和特定的WAD心律失常检测算法导致WAD恢复为无法识别该心律失常，从而导致患者死亡。我们确定了故障的可能原因，并提出了未来预防此类事件发生的方法。
