Question

In a normal ECG tracing,the T wave represents the
A) repolarization of the atria
B) depolarization of the atria
C) repolarization of the ventricles
D) depolarization of the ventricles

Accepted Answer

The T wave represents the repolarization of the ventricles. This occurs after the ventricles have contracted and expelled blood into the arteries. Repolarization is the process by which the cardiac muscle cells return to the resting state after depolarization (contraction). The T wave is typically a small, rounded wave that follows the QRS complex, which represents the depolarization of the ventricles.
