Is myocardial repolarization duration associated with repolarization heterogeneity?

ConclusionRepolarization duration as measured by JTpkc is not positively associated with dispersion of repolarization as measured by TpTe or QTd. Dispersion of repolarization may not be a critical mechanistic link between QTc prolongation and TdP.
