1. A method for adjusting the timing of a cardiac treatment device, comprising:

  • providing an implantable device comprising a first programmable timing, a first implanted sensor system having a first sensory modality comprising intracardiac dynamic impedance, and a second implanted sensor system having a second sensory modality, different from the first sensory modality;

    detecting a first valve mechanical event time from the first implanted sensor system;

    detecting a second valve mechanical event time from the second implanted sensor system;

    generating a comparison value based upon the first valve mechanical event time and the second valve mechanical event time;

    comparing the comparison value to a target value; and

    adjusting the first programmable timing based upon the difference between the comparison value and the target value.
