EKG Question #18


On the electrocardiogram, which complex indicates repolarization of the ventricles?


  1. The P wave
    • Rationale:
  2. The PR interval
    • Rationale:
  3. The QRS interval
    • Rationale:
  4. The T wave
    • Rationale:



The T wave represents the repolarization of the ventricles. It is slightly asymmetrical and follows the QRS. Downward, upward peaks, inversion, and abnormal associations with the ST segment (elevated, depressed) may indicate life-threatening disease or provide information to other conditions/illnesses.
