Left ventricular assist devices (LVADs) provide an effective means of managing advanced pump failure as a means of bridging to cardiac transplantation or as permanent therapy. Although ventricular arrhythmias remain common post-LVAD implantation, such therapy may allow malignant arrhythmias to be tolerated hemodynamically. This report describes the clinical findings in a patient who had likely been in a ventricular tachyarrhythmia for several days and presented in ventricular fibrillation, ambulatory, and mentating normally. This report, with previous similar reports, is additive to the body of evidence that LVADs alter the physiologic impact of ventricular arrhythmias in advanced heart failure and highlights the need for thoughtful programming of implantable cardioverter defibrillator therapies in these patients.
左心室辅助装置 (LVAD) 提供了一种有效的管理晚期泵衰竭的方法,可以作为心脏移植的桥接治疗或作为永久性治疗。尽管植入 LVAD 后仍然常见室性心律失常,但这种治疗可能允许恶性心律失常在血流动力学上得到耐受。本报告描述了一例患者的临床发现,该患者可能已经经历了数天的室性心动过速,并出现了室颤,同时保持正常的活动和神志。本报告与以前的类似报告一起,增加了 LVAD 改变晚期心力衰竭中心律失常生理影响的证据,并强调了在这些患者中对植入式心脏复律除颤器治疗进行深思熟虑编程的必要性。
