On ecg can qtc be higher if heart rate is lower?my hr was 59 qtc 416. i am a 29 year old male. ecg is otherwise normal.

Corrected QT: The QT interval is dependent on the underlying heart rate. As the heart rate increases the measured QT rate shortens (so that the heart is "reset" for the next beat faster). The formula for QT correction is based on adjustment for this. I have attached a link to a QTC calculator, so that you can plug in and see how the QTC changes with HR. https://www.mdcalc.com/corrected-qt-interval-qtc
