Abstract

Two formulations of the inverse problem of electrocardiography are presented which implicitly contain physiologically based spatio-temporal constraints. One formulation is based on the UDL model of ventricular activation, the other on a new, well posed formulation of the inverse problem. When applied to data of a WPW patient, results show agreement with invasive information regarding the site of pre-excitation, right ventricular epicardial breakthrough and termination of activation
