1. A system for providing baroreflex stimulation, comprising:
- a heart rate monitor to sense a heart rate and provide a signal indicative of the heart rate; and
a baroreflex stimulator, including;
a pulse generator to intermittently generate a stimulation signal to provide baroreflex stimulation for a baroreflex therapy; and
a modulator to adjust the stimulation signal based on the signal indicative of the heart rate such that the stimulation signal provides a desired baroreflex stimulation corresponding to a desired heart rate.

Abstract
The present invention is a system for providing baroreceptor stimulation comprising, a sensor to sense a physiologic parameter and provide a signal indicative of the physiologic parameter, a baroreceptor activation device, which includes, a pulse generator to intermittently generate a stimulation signal to provide baroreceptor stimulation for a baroreflex therapy, and a control system to adjust the stimulation signal based on the signal indicative of the physiologic parameter such that the stimulation signal provides a desired baroreceptor stimulation corresponding to a desired physiologic parameter.
