Ventricular repolarization is a much slower process than ventricular depolarization. Therefore, the T wave is broader than the QRS complex. Its configuration is also simpler and more rounded, like the silhouette of a gentle hill compared to the sharp, jagged, and often intricate contour of the QRS complex. Except with certain pathologic conditions, which we will explore later, the voltage of the T wave is less than that of the Q wave.
