The T wave on an ECG trace is created by the spread of ventricular repolarisation.

Question

BlackTom AI · Accepted Answer

This true/false item asks about the origin of the T wave on an ECG.
Option 1: True. The T wave represents ventricular repolarization. It reflects the process by which ventricular myocardial cells regain their resting electrical state after contraction, and its morphology arises from the sequence and timing of repolarization across the ventricular wall (endocardium to epicardium) and regional differences in action potential duration.
Option 2: False. If one chose false, they would be suggesting that the T wave does not relate to ventricular repolarization, which contradicts standard ECG physiology where the T wave is specifically linked to the return of the ventricles to their resting state after depolarization.
In summary, the T wave is an ECG manifestation of ventricular repolarization, and therefore the statement is correct.
