Because of its inverse relationship to heart rate, the QT interval is routinely transformed (normalized) by means of various formulae into a heart rate independent corrected value known as the QTc interval. The QTc interval is thus intended to represent the QT interval at a standardized heart rate (essentially the QT interval at a heart rate of ...
In this article, Iâll answer these. questions plus show you how to measure. the QT interval and how to recognize the. types of long QT syndrome (LQTS) and. their symptoms, causes, and treatments. The long and short of it. The QT interval on the ECG is measured. from the beginning of the QRS complex to. the end of the T wave (see ECG components). It represents the time it takes. for the ventricles of the heart to. depolarize and repolarize, or to. contract and relax.
