Automatic baroreflex modulation based on cardiac activity
First Claim
1. A system for providing baroreflex stimulation, comprising:
- a cardiac activity monitor to sense cardiac activity and provide a signal indicative of the cardiac activity; and
a baroreflex stimulator, including;
a pulse generator to provide a baroreflex stimulation signal adapted to provide a baroreflex therapy; and
a modulator to receive the signal indicative of the cardiac activity and modulate the baroreflex stimulation signal based on the signal indicative of the cardiac activity to change the baroreflex therapy from a first baroreflex therapy to a second baroreflex therapy.

Abstract
An aspect of the present subject matter relates to a system for providing baroreflex stimulation. An embodiment of the system comprises a cardiac activity monitor to sense cardiac activity and provide a signal indicative of the cardiac activity, and a baroreflex stimulator. The stimulator includes a pulse generator and a modulator. The pulse generator provides a baroreflex stimulation signal adapted to provide a baroreflex therapy. The modulator receives the signal indicative of the cardiac activity and modulates the baroreflex stimulation signal based on the signal indicative of the cardiac activity to change the baroreflex therapy from a first baroreflex therapy to a second baroreflex therapy. Other aspects are provided herein.
