AUTOMATIC BAROREFLEX MODULATION BASED ON CARDIAC ACTIVITY
First Claim
1. A method for operating an implantable medical device, comprising:
- receiving a signal indicative of sensed activity;
automatically classifying the sensed activity as an activity level selected from at least two defined activity levels preprogrammed in the implantable medical device;
automatically selecting a baroreflex stimulation level based on the activity level of the detected activity, wherein the baroreflex stimulation level is selected from at least two defined baroreflex stimulation levels preprogrammed in the implantable medical device; and
automatically delivering a baroreflex therapy using the baroreflex stimulation level.

Abstract
An aspect 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.

16. A method for operating an implantable medical device, comprising:
-
receiving a signal indicative of sensed activity, wherein the signal indicative of sensed activity includes a signal indicative of heart rate, respiration or acceleration; automatically classifying the sensed activity as an activity level selected from at least two defined activity levels preprogrammed in the implantable medical device, wherein the at least two defined activity levels preprogrammed into the implantable medical device includes rest and exercise, wherein automatically classifying the detected activity includes automatically classifying the detected activity as rest or exercise; automatically selecting a baroreflex stimulation level based on the activity level of the detected activity, wherein the baroreflex stimulation level is selected from at least two defined baroreflex stimulation levels preprogrammed in the implantable medical device; and automatically delivering a baroreflex therapy using the baroreflex stimulation level, wherein automatically delivering a baroreflex therapy includes automatically applying baroreflex stimulation during rest and automatically withdrawing baroreflex stimulation during exercise. - View Dependent Claims (17)

18. A method for operating an implantable medical device, comprising:
-
receiving a signal indicative of sensed activity; automatically classifying the sensed activity as an activity level selected from at least two defined activity levels preprogrammed in the implantable medical device, wherein the at least two defined activity levels preprogrammed into the implantable medical device includes a first activity level and a second activity level where the first activity level is higher than the second activity, wherein automatically classifying the detected activity includes automatically classifying the detected activity as the first activity level or the second activity level; automatically selecting a baroreflex stimulation level based on the activity level of the detected activity, wherein the baroreflex stimulation level is selected from at least two defined baroreflex stimulation levels preprogrammed in the implantable medical device, wherein automatically selecting a baroreflex stimulation level includes automatically selecting a first baroreflex stimulation level when the activity level is determined to be the second activity level and automatically selecting a second baroreflex stimulation level when the activity level is determined to be the first activity level, wherein the first baroreflex stimulation level is higher than the second baroreflex stimulation level; and automatically delivering a baroreflex therapy using the baroreflex stimulation level, wherein the defined baroreflex stimulation levels preprogrammed in the implantable medical device have an inverse relationship with the defined activity levels preprogrammed in the implantable medical device such that an incremental increase in the activity level corresponds with an incremental decrease in the baroreflex stimulation level. - View Dependent Claims (19, 20)
