1. A method of monitoring ventricular capture in a ventricular cardiac resynchronization therapy (CRT) delivery device to promote mechanical synchrony between ventricular chambers, comprising:

  • suspending a CRT delivery regimen;

    verifying an absence of possibly deleterious cardiac rhythms, and after successfully verifying the absence of possibly deleterious cardiac rhythms;

    conducting a ventricular conduction test to a first ventricle, wherein the first ventricle receives pacing stimulation;

    monitoring a second ventricle during a period of time following , wherein said second ventricle is free of direct pacing stimulation, for inter-ventricular conduction of said pacing stimulation from said first ventricle.
