WebWhat is a QT. The QT interval is a measurement that represents the total time from ventricular depolarization to complete repolarization. This process begins at the start of the q wave and extends to the end of the T wave. If there is no q wave, then the starting point would be the very beginning of the R wave. WebThe QTc interval is considered prolonged at and above 450 milliseconds for men, and at and above 470 milliseconds for women. The QTc interval can prolong when the electrical system in the bottom of the heart is not working properly. This is commonly seen as a side effect of some medications.
