There is no distinctly visible wave representing atrial repolarization in the ECG because it occurs during ventricular depolarization. Because the wave of atrial repolarization is relatively small in amplitude (i.e., has low voltage), it is masked by the much larger ventricular-generated
Is atrial repolarization on ECG?
Atrial and ventricular depolarization and repolarization are represented on the ECG as a series of waves: the P wave followed by the QRS complex and the T wave. The first deflection is the P wave associated with right and left atrial depolarization. Wave of atrial repolarization is invisible because of low amplitude.
Where does atrial repolarization occur on ECG?
As the human Ta wave of atrial repolarization occurs during the PR segment and QRS complex, it is not observed and recorded widely in sinus rhythm subjects by the standard 12-lead ECG (1).
