The considerable progress achieved in the inverse problem of electrocardiography over the
last decade has provided grounds for optimism about the possibility of approaching …

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 Activation mapping using noninvasive electrocardiographic imaging (ECGi) has
recently been used to describe the physiology of different cardiac abnormalities. These …

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

A device for measuring parameters of human tissue includes a multielectrode catheter for
taking multiple measurements of the electrical characteristics of the human tissue, a …

OBJECTIVES/BACKGROUND: Cardiac arrhythmias are a leading cause of death and
disability. Electrocardiographic imaging (ECGI) is a noninvasive imaging modality that …

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

The electrocardiographic inverse problem of computing epicardial potentials from multi-
electrode body-surface ECG measurements, is an ill-posed problem. Tikhonov …

Potential-based inverse electrocardiography is a method for the noninvasive computation of
epicardial potentials from measured body surface electrocardiographic data. From the …

Background—The last decade witnessed an explosion of information regarding the genetic,
molecular, and mechanistic basis of heart disease. Translating this information into clinical …
