First Claim
Patent Images
1. A method of mapping a volumetric electrical potential distribution of a heart chamber arising from electrical activation in a myocardium comprising the steps of:
- a) positioning an electrode array within the heart chamber;
b) determining heart chamber volume and shape;
c) computing the position of said array within said heart chamber;
d) measuring electrical potentials on said array;
e) computing the three-dimensional volumetric electrical field distribution of said heart chamber volume from a spherical harmonic series expression containing said measured electrical potentials, and said array position; and
f) displaying said volumetric electrical field distribution.

Abstract
A method of mapping electrical activity of a patient'"'"'s heart. The system includes a set of electrodes spaced from the heart wall and a set of electrodes in contact with the heart wall. Voltage measurements from the electrodes are used to generate three-dimensional and two-dimensional maps of the electrical activity of the heart.
