Baroreflex modulation based on monitored cardiovascular parameter
First Claim
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
An aspect of the present subject matter relates to a system for providing baroreflex stimulation. An embodiment of the system comprises a heart rate monitor to sense a heart rate and provide a signal indicative of the heart rate, and a baroreflex stimulator. The stimulator includes a pulse generator to intermittently generate a stimulation signal to provide baroreflex stimulation for a baroreflex therapy, and further includes 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. Other aspects are provided herein.

14. A system for providing baroreflex stimulation, comprising:
-
a baroreflex stimulator, including;
a pulse generator to generate a stimulation signal to provide intermittent baroreflex stimulation for a baroreflex therapy; and
a modulator to adjust the stimulation signal;
a cardiovascular parameter monitor to monitor at least one cardiovascular parameter and provide a first signal indicative of the cardiovascular parameter during the baroreflex stimulation and a second signal indicative of the cardiovascular parameter without the baroreflex stimulation; and
a comparator to provide a detected change for the cardiovascular parameter based on the first and second signals, and to provide a therapy control signal based on a desired change for the cardiovascular parameter and the detected change. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A baroreflex stimulator, comprising:
-
means for intermittently providing baroreflex stimulation for a baroreflex therapy over a period of time;
means for comparing values for at least one cardiovascular feedback parameter when the baroreflex stimulation is applied and when then baroreflex stimulation is not applied to provide a detected feedback change;
means for comparing the detected feedback change to a desired feedback change to provide a comparison result; and
means for adjusting the baroreflex stimulation based on the comparison result to control the baroreflex therapy over the period of time. - View Dependent Claims (23, 24, 25)
