ABSTRACT:
A system (10) for determining electrical potentials on an endocardial surface of a heart is provided. The system includes a non-contact, non-expandable, miniature, multi-electrode catheter probe (12), a plurality of electrodes (32) disposed on an end portion (30) thereof, means for determining endocardial potentials (14) based on electrical potentials measured by the catheter probe, a matrix of coefficients that is generated based on a geometric relationship between the probe surface, and the endocardial surface. A method is also provided.
