If QRS complex and T wave represent depolarization and repolarization of ventricles respectively; why is T wave wider and smaller than QRS complex?

Question

Quizplus · Accepted Answer

Repolarization is slower than depolarization, which leads to a wider T wave compared to the QRS complex. The force of contraction (A) and the composite nature of the QRS complex (D) are not relevant to the width and size differences between the QRS complex and T wave. While the T wave may be influenced by the depolarization of the atria, it primarily represents repolarization of the ventricles, so C is not a suitable answer.
