title: Mystery of QTc interval dispersion.
abstract: Reporting QTc dispersion values without paying attention to the original QT dispersion values and to the heart rate may be seriously misleading because differences in QTc dispersion between clinically well-defined populations may only be caused by differences in the underlying heart rate. This is demonstrated by showing the significant differences in "heart-rate corrected" length of the surname between long-term survivals and nonsurvival patients of acute myocardial infarction.
