Linear inverse approaches for the reconstruction of epicardial and transmembrane potential patterns

Abstract

In this study we compare two different linear inverse approaches to the inverse problem of electrocardiography. Method A is the standard Tikhonov zero order approach used as a reference method.. Method B is based on the general deconvolution theorem proposed by Greensite. Both methods are applied to both the epicardial potential and the transmembrane potential considered as the primary source. In order to compare the performance of both methods the activation time pattern is estimated.
