Repol Loc shows improved localization of repolarization changes, reducing misinterpretation by 26.12% compared to 18.66% using ARI.
Elevated correlation to optical action potential duration achieved by Repol Loc (slope=0.90) vs. ARI (slope=0.79).
Assessment using optical mapping and generalized linear models validates detection of repolarization alternans changes.
These findings support Repol Loc as a superior clinical mapping tool for identifying myocardial spatiotemporal repolarization gradients.
