Ventricular arrhythmias are life-threatening and can serve as a precursor to sudden death. They are a common presentation in patients with severely reduced left ventricular (LV) function. The use of an implantable cardioverter defibrillator (ICD) is seen as an acceptable therapy against malignant ventricular arrhythmias. In patients with LV heart failure, a left ventricular assist device (LVAD) can provide pulsatile flow to mimic the cardiac systolic and diastolic function. We report a case of a 38-year-old male with a LVAD who presented to the emergency department due to syncope and frequent ICD discharges. There were documented episodes of ventricular fibrillation and a failed defibrillator threshold test.
室性心律失常危及生命，可作为猝死的先兆。它们在左心室（LV）功能严重减退的患者中很常见。植入式心脏复律除颤器（ICD）的使用被视为对抗恶性室性心律失常的可接受疗法。在左心室心力衰竭患者中，左心室辅助装置（LVAD）可提供搏动性血流以模拟心脏的收缩和舒张功能。我们报告一例38岁男性LVAD患者，因晕厥和频繁的ICD放电就诊于急诊科。记录到室颤发作且除颤阈值测试失败。
