A member asked:
Qtc interval 483. is this serious?
A doctor has provided 1 answer
Normal: Your QTc is on the upper end of normal range, < 500 ms. The QT or QTc changes based on your heart rate and other factors. Some medications can make the QT longer (some antibiotics, some psychiatric medications, some heart medications, as well as others) so it is important that you talk to your doctor about it to make sure you don't take any of these. Also discuss family history of heart attacks.
