Abstract:
1. A system for providing neural stimulation to a neural target in an autonomic nervous system of a patient to provide a heart failure therapy to the patient, comprising: an activity monitor configured to sense activity of the patient and provide a signal indicative of a sensed activity level; an electrode configured for use to deliver the neural stimulation to the neural target; a neural stimulator, including: a controller configured to store a circadian rhythm template for the patient and to store a mapping of a plurality of activity levels to a plurality of neural stimulation intensity levels, wherein a given activity level is mapped to at least a first neural stimulation intensity and a second neural stimulation intensity level, and for the given activity level, the controller is configured to receive the signal and control the modulator to deliver the neural stimulation at intensity levels mapped to the given activity level, and wherein the controller is configured to use the circadian rhythm template to deliver the neural stimulation at a first programmed burst pattern for the given sensed activity level at a first time of a day and to deliver the neural stimulation at a second programmed burst pattern for the given sensed activity level at a second time of the day.
