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.
