Question

BlackTom AI · Accepted Answer

The question asks which wave on an ECG represents the repolarization of the ventricles, and provides four choices: T, R, P, Q.
Option T: This is the wave that corresponds to ventricular repolarization. The T wave appears after the QRS complex and indicates the ventricles returning to their resting electrical state, which aligns with repolarization.
Option R: The R wave is the positive deflection within the QRS complex and reflects ventricular depolarization, not repolarization. Misinterpreting this would confuse the major activation of the ventricles with their recovery.
Option P: The P wave represents atrial depolarization, not ventricular activity. Since atrial activity is separate from the ventricular repolarization process, this choice does not fit the question.
Option Q: The Q wave is the initial downward deflection of the QRS complex and is part of ventricular depolarization. It is not a representation of ventricular repolarization by itself, so it does not answer the prompt.
In summary, recognizing the sequence of ECG components—P for atrial depolarization, QRS for ventricular depolarization, and T for ventricular repolarization—helps distinguish why T is the correct association with ventricular repolarization, while the other waves pertain to other phases of the cardiac cycle.
