    摘要: A system and method is provided for non-invasively determining electrical activity of the heart of a human being. Electrical potentials are measured on the body surface via an electrode vest (12), and a body surface potential map is generated. A matrix of transformation based on the geometry of the torso, the heart, locations of electrodes, and position of the heart within the torso is also determined with the aid of a processor (24), and a geometry determining device (26). The electrical potential distribution over the epicardial surface of the heart is then determined based ona regularized matrix of transformation, and the body surface potential map. Using the epicardial potential distributions, epicardial electrogram, isochronal are also reconstructed, and displayed via an output device (28).

    摘要: A computer-implemented method for electrocardiographic imaging (ECGI) is provided. The method includes computing a transfer matrix, measuring a plurality of electrical potentials, and computing an estimation of electrical potentials on a surface of interest based at least in part on the measured potentials and the computed transfer matrix. The transfer matrix computing step is performed prior to the measuring step.

    摘要: Noninvasive systems and methods are provided for determining electrical activity for a heart of a living being. A processor is configured to meshlessly compute data that represents heart electrical activity from a set of noninvasively measured body surface electrical potentials. This is accomplished using data that describes a geometric relationship between a plurality of locations corresponding to where the body surface electrical potentials were measured and the heart.
