Using bazett formula when my heart rate is 98 my qt is 350 and qtc 447. but when my heart rate is 60 it is 398. why is it 447 at higher rate?
A doctor has provided 1 answer
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.

My son's ECG report showed 93 heart rate per minute, pr 144ms , qrs 82 , s p-r-t 57 12 18. But the qt/qtc is 366/455.Borderline. I am scared .Please rep?
Heart Rate 96 QRS Interval 82 ms QT Interval 364 ms QTC Interval 460 ms P Axis 61 deg QRS Axis 21 deg T Wave Axis 7 deg P-R Interval 184 msec
Is it true that it takes 1-2 minutes for the qt interval to adapt to a new heart rate? ime if resting heart rate is 60 supine qtc 395 and you stand up the instant tachycardia would show a false prolonged qtc as it hasn't had time to adapt fully?
