Abstract:
A computer usable medium having computer readable program code embodied therein for configuring a computing system to map a volumetric electrical potential distribution of a heart chamber arising from electrical activation in a myocardium, the medium comprising:a) computer readable program code configured to cause a computer to receive first inputs relating the volume and shape of the heart chamber; b) computer readable program code configured to cause a computer to calculate the heart chamber volume and shape based upon the first inputs; c) computer readable program code configured to cause a computer to receive second inputs related to the position of an electrical array located within the heart chamber; d) computer readable program code configured to cause a computer to calculate the position of said array within said heart chamber based upon the second inputs; e) computer readable program code configured to cause a computer to receive third inputs relating directly to the electrical potentials received by electrodes on said array; and f) computer readable program code configured to cause a computer to calculate from said third inputs 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.
