As a domain expert in cardiology, I can explain the concept of ventricular repolarization. Ventricular repolarization is a critical phase in the cardiac cycle that follows depolarization. During depolarization, the ventricles of the heart are stimulated to contract, which pumps blood out into the body. Repolarization is the process by which the ventricles return to their resting state after this contraction. In the context of an electrocardiogram (ECG), the ventricular repolarization is represented by the T wave. The T wave is the small peak that follows the larger QRS complex, which represents ventricular depolarization. The T wave signifies that the ventricles are returning to their resting membrane potential, which is a negative value. This is the opposite of depolarization, where the membrane potential becomes positive as the heart muscle cells are stimulated to contract. So, to summarize, ventricular repolarization is the process where the heart's ventricles revert to their resting state after contraction, and it is depicted by the T wave on an ECG.

After the QRS complex, we see another small peak, and this is called the T wave. The T wave represents the repolarization of the ventricles. We know that repolarization is the opposite of depolarization and refers to the change of the membrane potential that returns the membrane back to a negative value.
