1. A method comprising:
- providing a mechanical activation time (MA time) for a myocardial location, the location defined at least in part by an electrode, and the mechanical activation time determined at least in part by movement of the electrode, wherein the mechanical activation time comprises a time determined based on position data for the electrode wherein the electrode measures potential in a current field;
providing an electrical activation time (EA time) for the myocardial location wherein the electrical activation time comprises a time determined by electrical cardiac activity data acquired using the electrode over at least a portion of a cardiac cycle; and
determining an electromechanical delay (EMD) for the myocardial location based on a difference between the mechanical activation time (MA time) and the electrical activation time (EA time).
