QTc: The formula only estimates the corrected qt and it includes the square root of the heart rate as the denominator of the denominator or in other words the corrected QT interval will trend in the same direction, the higher the rate , the higher the QTc.

I am sorry, you might be miscalculating them as the qt is supposed to decrease at higher rates.
