Abstract:
1. A method implemented by an implantable medical device, comprising: generating a stimulation signal in a recurring succession of stimulation cycles and stimulating an autonomic neural target using the generated stimulation signal, wherein generating the stimulation signal includes generating the stimulation signal for a portion of each stimulation cycle and not generating the stimulation signal for another portion of each stimulation cycle, wherein stimulation of the autonomic neural target affects a cardiovascular parameter; using a physiological sensor to obtain a first value for a cardiovascular feedback parameter corresponding to the portion of each cycle when the stimulation cycle is generated and a second value corresponding to the other portion of each cycle when the stimulation cycle is not generated; determining a detected feedback change between the portions of the stimulation cycle, wherein determining the feedback change includes comparing the first value to the second value; comparing the detected feedback change to a target change to provide a comparison result; and adjusting the stimulation signal using the comparison result.
