Overview

Explanation

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.
