Claim 18:
19. The method of claim 18, wherein the number of electrodes and the placement of the electrodes is determined by:
generating a 3D mesh of at least part of the heart from a 3D model of at least part of the heart of the patient, or using a generic 3D model of the heart to obtain a 3D mesh of at least a part of the heart, the 3D mesh of at least a part of the heart comprising a plurality of nodes;
aligning the 3D mesh of at least part of a heart to images of the heart of the patient;
placing additional nodes onto the 3D mesh corresponding to a location of at least two electrodes on the patient;
calculating a propagation velocity of the electrical activation between the nodes of the 3D mesh corresponding to the location of the at least two electrodes;
extrapolating the propagation velocity to all of the nodes of the 3D mesh;
calculating a degree of parallel activation of the myocardium for each node of the 3D mesh; and
determining the optimal electrode number and position on the heart of the patient based on the node(s) of the 3D mesh with a calculated degree of parallel activation of the myocardium above a predetermined threshold.
