Objective The purpose of this study was to evaluate the accuracy of noninvasive reconstructions of epicardial potentials, electrograms, activation and recovery isochrones, and beat origins by simultaneously performing electrocardiographic imaging (ECGI) and invasive epicardial electrography in intact animals. Background Noninvasive imaging of electrical potentials at the epicardium, known as ECGI, is increasingly applied in patients   Read More …

The inverse problem of electrocardiography aims at noninvasively reconstructing electrical activity of the heart from recorded body-surface electrocardiograms. A crucial step is regularization, which deals with ill-posedness of the problem by imposing constraints on the possible solutions. We developed a regularization method that includes electrophysiological input. Body-surface potentials are recorded and a computed tomography scan   Read More …

Recently, we have published a review about noninvasive reconstruction of cardiac electrical activity. In this review, we aim at providing both an overview of the technical background and clinical application of a broad range of noninvasive inverse imaging techniques.
