Abstract

A method for mapping electrical activity of a heart includes inserting a probe into a chamber of the heart, the probe including at least one position sensing device and a plurality of non-contact electrodes. Position coordinates of the electrodes are determined relative to an endocardial surface of the chamber, using the at least one position sensing device, and electrical potentials are measured at the determined position coordinates using the electrodes. Electrical potentials are computed at a plurality of points on the endocardial surface, using the measured potentials and the position coordinates, so as to generate a map of electrical activity over the endocardial surface based on the computed potentials.
