A comparison of techniques for the inverse problem of electrocardiography applied to data from six isolated rabbit heart experiments

Singular Value Decomposition (SVD) and Generalized Eigensystem (GES) inverse techniques are compared for their ability to solve the inverse problem of electrocardiography. In this study, epicardial data from six in-vitro rabbit heart experiments are used to project body surface data for six different geometries. For concentric geometries, GES outperformed SVD in all instances. For eccentric heart/body geometries, GES outperformed SVD when the inverse errors themselves were small
