System for neurally-mediated anti-arrhythmic therapy

摘要

A system is provided, comprising: a sensor adapted to detect a predetermined cardiac activity indicated for a defibrillation shock; a vagal nerve stimulator adapted to deliver vagal nerve stimulation; and a defibrillator adapted to subcutaneously deliver the defibrillation shock. Vagal nerve stimulation (102) may be provided to lower a defibrillation threshold (DFT) in preparation for the defibrillation shock. Various embodiments apply prophylactic vagal nerve stimulation (104) either in addition to the nerve stimulation therapy to lower DFT, or as a therapy without the nerve stimulation therapy to lower DFT.
