Increase in qtc interval
WebThe 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. The QT interval is affected by many things. WebA long QT interval is diagnosed by ECG showing prolongation of the rate-corrected QT interval (QTc). Normal QTc intervals are about 0.40 second for men and 0.41 second for women and are considered prolonged when > 0.47 second for men or > 0.48 second for women.
