1. A method comprising:

  • delivering a cardiac resynchronization therapy that comprises an atrio-ventricular delay parameter and an interventricular delay parameter;

    measuring an intrinsic atrio-ventricular conduction delay;

    measuring an intrinsic interventricular conduction delay;

    assessing heart failure status based at least in part on the measured atrio-ventricular conduction delay and the measured interventricular conduction delay; and

    adjusting at least one of the atrio-ventricular delay parameter value and the interventricular delay parameter value based at least in part on the measured atrio-ventricular conduction delay and the measured interventricular conduction delay.
