1. A method for use with an implantable medical device for determining ventricular contraction intervals, the method comprising:

  • detecting a left atrial pressure (LAP) signal;

    identifying a c-wave in the detected LAP signal;

    detecting a right ventricular pressure (RVP) signal;

    identifying an upstroke point in the RVP signal;

    determining an interventricular mechanical delay based in part on a time interval between the upstroke point in the RVP signal and the c-wave in the LAP signal; and

    controlling therapy delivered by the implantable medical device based on the interventricular mechanical delay.
