1. A method for selecting a pacing therapy site, comprising:

  • pacing at each of a plurality of pacing sites along a heart chamber;

    acquiring from a signal of mechanical heart activity a change from a baseline mechanical activity during the pacing at each of the plurality of pacing sites along the heart chamber;

    acquiring from a signal of electrical heart activity a change from a baseline electrical activity during the pacing at each of the plurality of pacing sites along the heart chamber;

    sorting the plurality of pacing sites in a first order based upon the changes in mechanical heart activity;

    sorting the plurality of pacing sites in a second order based upon the changes in electrical heart activity; and

    selecting a pacing site from the plurality of pacing sites as a common pacing site between the first order and the second order.
