DOI: 10.1007/s00380-019-01383-4

Abstract: AbstractMyocardial ischemia changes the electrophysiological properties of the myocardium, but it is difficult to detect the abnormalities of depolarization and repolarization noninvasively in patients with coronary artery disease. Depolarization and repolarization abnormalities were retrospectively investigated… read more here.

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: 10.1016/j.jelectrocard.2022.04.001

Abstract: PURPOSE Cardiac resynchronization therapy (CRT) reduces ventricular activation times and electrical dyssynchrony, however the effect on repolarization is unclear. In this study, we sought to investigate the effect of CRT and left ventricular (LV) remodeling… read more here.

DOI: 10.1016/j.media.2021.102075

Abstract: Reliable patient-specific ventricular repolarization times (RTs) can identify regions of functional block or afterdepolarizations, indicating arrhythmogenic cardiac tissue and the risk of sudden cardiac death. Unipolar electrograms (UEs) record electric potentials, and the Wyatt method… read more here.
