Electrical activity at the level of the heart muscle can be noninvasively reconstructed from
body-surface electrocardiograms (ECGs) and patient-specific torso-heart geometry. This …

Background: Cardiac arrhythmias continue to be a leading cause of death and disability.
Despite this alarming fact, a noninvasive imaging modality for cardiac electrophysiology …

This book on modelling the electrical activity of the heart is an attempt to describe continuum
based modelling of cardiac electrical activity from the cell level to the body surface (the …

Background The goal of noninvasive electrocardiographic imaging (ECGI) is to determine
electric activity of the heart by reconstructing maps of epicardial potentials, excitation times …

Background—A recent study demonstrated the ability of electrocardiographic imaging
(ECGI) to reconstruct, noninvasively, epicardial potentials, electrograms, and activation …

The aim of this study was to quantify the effects of selected inhomogeneities and
anisotropies on computed electric potential fields associated with the electrocardiographic …

Background—The relationship between epicardial and body surface potentials defines the
forward problem of electrocardiography. A robust formulation of the forward problem is …

Torso Effects on Reconstructed Epicardial Potentials. Introduction: Noninvasive
electrocardiographic imaging (ECGI) involves inverse reconstruction of epicardial potentials …

An analytic, eccentric-spheres model was used to test the efficacy of different regularization
techniques based on the Tikhonov family of regularizers. The model, although simple …

In very broad terms, the inverse problem of electrocardiography may be defined as the
determination of the electrical function of the heart from a number of remote recordings of …
