1. A system for providing optimized cardiac chamber synchronization to a patient during delivery of cardiac pacing therapy, comprising:

  • means for sensing a depolarization event of and/or providing a pacing stimulus to at least two chambers of a heart;

    a single means for sensing acceleration, velocity or displacement of only a portion of an interchamber septal wall tissue of the heart disposed between said at least two chambers of the heart and providing a displacement signal thereof to the means for sensing a depolarization event and/or providing pacing stimulus; and

    means for adjusting the timing for providing pacing stimulus to said heart to reduce or maintain the magnitude of the sensed displacement signal.
