T wave ventricular depolarization
WebWe will now describe some important ECG wave characteristics, central to the development of signal processing algorithms, along with the wave-naming convention. Atrial … WebThe Q-T interval, as its name suggests, measures the time from the start of the Q wave to the end of the T wave. This measures the time for depolarization and repolarization, or contraction and relaxation, of the heart’s ventricles. The Q-T interval is dependent upon heart rate: a faster heart rate results in a shorter Q-T interval.
