In an ecg trace, during the t wave, which of the following is true?
a. only the left ventricle is repolarizing
b. both ventricles are depolarizing
c. none of the choices are correct.
d. the atria are repolarizing.
e. both ventricles are repolarizing.

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.
