Abstract
According to an embodiment of a method, a predetermined cardiac activity indicated for an antitachycardia shock is detected. Neural stimulation is applied to lower a defibrillation threshold in preparation for the shock, and the shock is subcutaneously delivered. According to one embodiment, neural stimulation is applied as part of a prophylactic therapy. A predetermined cardiac activity indicated for an antitachycardia shock is detected, and the shock is subcutaneously delivered. Other aspects and embodiments are provided herein.
