Answer:
The correct answer will be option E- Both ventricles are repolarizing.
Explanation:
The electrocardiogram or ECG is a representation of the electrical activity of the heart that is used for the diagnostic purpose of heart.
The electrical signals are represented in the form of waves- PQRST.
The T waves are slightly asymmetric which follow the same direction as of QRS waves. The T waves represent the ventricular repolarization ( the change of membrane potential back to a negative value). The repolarization of the membrane takes place in both the ventricles simultaneously which is represented as T wave.
Thus, option E- is the correct answer.
