Abstract:
A system for coordinating the stimulation of nerves for controlling the level of neurohormonal activation in a living body having a heart subject to potential or actual pathologic stress levels comprising:an implantable pulse generator with a microprocessor and memory adapted and disposed to run a plurality of processes,a sensor for sensing SVO.sub.2 in the body, and a sensor for determining pressure in a ventricle of the heart of the body, both said sensors adapted and disposed to provide readings to said microprocessor for use by said processes,a bradycardia pacer control process included within said pulse generator for pacing the heart when a condition of bradycardia is present so as to prevent insufficient heart rate by said heart,at least one stimulation electrode connected to effectively deliver electrical stimulation to a baroreceptor nerve site,an adjustment process for monitoring heart rate and estimating PVR from said SVO.sub.2 and pressure so as to determine appropriate modifications to the stimulation output to said stimulation electrode, andmeans for making said modifications.
