In an ECG, the T-wave represents which of the following physiological events?
- A.Depolarization of the atria
- B.Depolarization of the ventricles
- C.Repolarization of the ventricles
- D.Repolarization of the atria
Show correct answer & step-by-step solution
Correct answer: C — Repolarization of the ventricles
Solution
- The P-wave represents atrial depolarization.
- The QRS complex represents ventricular depolarization.
- The T-wave represents the return of the ventricles from an excited to a normal state, known as repolarization.
- Hence the answer is (C).
