DOI: 10.1016/j.jelectrocard.2020.02.003
Abstract: BACKGROUND Measuring repolarization characteristics is challenging and has been reserved for experienced physicians. In electrocardiographic imaging (ECGI), activation-recovery interval (ARI) is used as a measure of local cardiac repolarization duration. We hypothesized that repolarization characteristics,… read more here.

DOI: 10.3389/fphys.2019.00273
Abstract: The electrocardiographic imaging (ECGI) inverse problem highly relies on adding constraints, a process called regularization, as the problem is ill-posed. When there are no prior information provided about the unknown epicardial potentials, the Tikhonov regularization… read more here.
