It indicates the time taken for ventricular depolarization and repolarization. The normal and pathological ECG » QT-Interval.The duration of the QT-interval varies according to the studied lead (50 ms on average between the shortest QT and the longest QT), due to a different projection of the depolarization and repolarization vectors.

Normal electrocardiogram in the newborn.Ventricular repolarization can be evaluated on the surface ECG by measuring the QT interval duration and by analysing the morphology of the ST segment and of the T wave. ContentsOverview of the normal electrocardiogram (ECG)QT duration and QTc durationQT duration reflects the total duration of ventricular depolarization and repolarization. QRS duration represents the time in which ventricular depolarization takes place. A normal QRS duration should be less than 0.08 sec (2 small squares wide).Question 3: What is the QT interval of this ECG, and is it normal for this heart rate?
