Noninvasive unipolar electrogram T-wave upslope is an accurate marker of local refractoriness in explanted hearts with drug-induced repolarization dispersion

Background: The relationship between T-wave morphology in local unipolar electrograms (UEGs) as mapped with noninvasive electrocar-diographic imaging (ECGI) and local repolarization time (RT) has not been validated in pronounced RT dispersion.
