1. A method comprising:

  • sensing motion of a heart contraction at a first heart to produce a first signal;

    sensing motion of the heart contraction at a second heart wall location to produce a second signal;

    comparing the first signal to the second signal to detect a difference in synchronization of the first heart wall location with respect to the second heart wall location; and

    iteratively adjusting a control parameter of a stimulation pulse to reduce the difference in synchronization.
