Which wave is typically associated with ventricular repolarization?

The T wave is typically associated with ventricular repolarization in the electrocardiogram (EKG). During the cardiac cycle, the repolarization of the ventricles is a crucial phase that follows depolarization, which is represented by the QRS complex. The T wave visually indicates this repolarization process; it reflects the resetting of the myocardial cells' electrical state after they have contracted and pumped blood.

In the context of the EKG, the T wave appears as a broad, rounded deflection that follows the QRS complex and precedes the next P wave, signaling the readiness of the ventricles to undergo another depolarization cycle. Understanding the characteristics and timing of the T wave is essential for interpreting cardiac rhythms and identifying potential abnormalities related to ventricular function.
