WebJun 30, 2024 · Ian Rowlandson: An electrocardiogram (ECG) measures the QT interval from the earliest onset of depolarization (the start of the Q wave) to the latest offset of repolarization (the end of the T wave)—or in simpler terms, the time it takes the heart to recharge between beats. A QT interval corrected for heart rate results in the QTc value ...

Identification of a prolonged heart rate … WebThe QT interval represents the time for both ventricular depolarization and repolarization to occur, and therefore roughly estimates the duration of an average ventricular action potential. This interval can range from 0.20 to 0.40 seconds depending upon heart rate. At high heart rates, ventricular action potentials shorten in duration, which decreases the QT …
