Heart rate variation: The length of time that it takes for the myocardium to repolarize varies with the heart rate. Faster heart rate, faster repolarization. Therefore, the absolute qt interval is not reliable, and some form of correction of the qt interval that varies with the heart rate is necessary to understand whether the rate of repolarization is normal. However, they are different methods and different math.
