yes

The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.

Atrial repolarization coincides with the QRS complex on the ECG.

The T-wave corresponds to Ventricular repolarization.

'with tHE t-wave' <-- WRONG

The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.

Precordial repolarization disturbance is a heart condition that can be determined though an EKG. Precordial has to do with the area above your heart and repolarization has to do with the heart muscle preparing itself for it's next beat.
