The QT interval indicates how fast the ventricles are repolarized and how fast they are ready for a new heart cycle. The normal value for QTc(orrected) is: '''below 450ms for men and below 460ms for women'''. <cite>aha2</cite> | The QT interval indicates how fast the ventricles are repolarized and how fast they are ready for a new heart cycle.
