1. A method of synchronizing a contraction of ventricular wall locations, the method comprising the steps of:

  • sensing motion with a first accelerometer located at a first ventricular wall location to produce a first signal;

    sensing motion with a second accelerometer located at a second ventricular wall location to produce a second signal;

    comparing the first signal to the second signal to detect a difference in synchronization of the first ventricular wall contraction and the second ventricular wall contraction; and

    determining, based on the detected difference in synchronization of the first ventricular wall contraction and the second ventricular wall contraction, at least one parameter for a stimulation pulse to be applied by an electrode.
