title: Relation between QT interval dispersion and heart rate.
abstract: Because the relation between QT dispersion (QTd) and heart rate (HR) are different from that between QT interval and HR, QTd could be overadjusted at a high HR and be underadjusted at a slow HR if we use Bazett's formula to adjust QTd. HR adjustment of QTd is not needed to evaluate repolarization dispersion.
