Claim Text:
1. An implantable neurostimulator-implemented method for managing tachyarrhythmias through vagus nerve stimulation, comprising the steps of: providing an implantable neurostimulator comprising a pulse generator configured to deliver electrical therapeutic stimulation in a manner that results in creation and propagation in both afferent and efferent directions of action potentials within neuronal fibers of the cervical vagus nerve of a patient; storing an operating mode of the pulse generator in a recordable memory, the storing comprising: therapeutically delivering the maintenance dose at the duty cycle to the vagus nerve prior to delivering the restorative dose, prior to sensing a condition of tachyarrhythmia, and independent of cardiac cycle, via the pulse generator of the implantable neurostimulator through helical electrodes electrically coupled to the pulse generator via a nerve stimulation therapy lead; monitoring a patient's normative physiology to sense the condition of tachyarrhythmia via a physiological sensor of the implantable neurostimulator, and upon sensing the condition of tachyarrhythmia, switching from delivering the maintenance dose to delivering the restorative dose at a higher duty cycle to the vagus nerve via the pulse generator through the pair of helical electrodes; and controlling the pulse generator to suspend delivery of either the restorative dose or the maintenance dose in response to a signal remotely applied to the implantable neurostimulator.
