Abstract

The inverse problem of electrocardiography is aimed at characterizing electrical activity within the heart muscle by harvesting remote-sensing data. Electrical potentials on the surface of the heart are obtained by solving a boundary value problem using the boundary element method in concert with a regularization technique. Use of adaptive regularization is demonstrated to be superior to traditional methods for solving the inverse problem. 1 Introduction The heart muscle contracts under a wave of electricity about once each second. The heart's electric field radiates inside its cavities as well as outside into the chest cavity, sending information about the heart's function. Images of the heart's electrical activation can be obtained by d
