1. A system comprising:

  • an implantable medical device comprising;

    a timing circuit;

    a cardiac impedance sensing circuit, coupled to the timing circuit, the cardiac impedance sensing circuit configured to detect a cardiac impedance signal;

    an acoustic sensor, coupled to the timing circuit, the acoustic sensor configured to sense an acoustic signal; and

    a heart sound detector circuit, coupled to the timing circuit, the heart sound detector circuit configured to detect a heart sound signal in the acoustic signal;

    wherein the timing circuit is configured to calculate a time interval between a point on the heart sound signal and a point on the cardiac impedance signal.
