2017 HRS/EHRA/ECAS/APHRS/SOLAECE expert consensus statement on catheter and surgical ablation of atrial fibrillation (2017, methodology): “A mathematical algorithm combines the body surface potentials recorded by the electrodes and the geometric information provided by CT and solves the electrocardiographic inverse problem in order to noninvasively obtain estimated epicardial electrograms.(221,570) An advantage of this approach is that”
Evaluation of a Rapid Anisotropic Model for ECG Simulation (2017, methodology): “Much simpler models are presently being used inside inverse models, which aim at recovering cardiac events from noninvasive signals (Ramanathan et al., 2004; van Dam et al., 2009; Tysler and Svehlikova, 2013; Wang et al., 2013; Erem et al., 2014), and in interactive ECG-simulation tools (van…”
Noninvasive Transmural Electrophysiological Imaging Based on Minimization of Total-Variation Functional (2014, background): “In exchange for a unique solution, a common assumption in existing approaches to electrophysiological imaging restricts the solutions to the surface of the heart, represented by the reconstruction of epicardial potential [7], [8] and the reconstruction of activation/recovery time on both the epicard”
