It is on page 374 of your lab book assuming this is the same question that came out Lab 28 in the Ninth Edition of Seeley's Anatomy & Physiology. The atrial repolarization occurs during ventricualr depolarization and is masked by the larger QRS complex. I actually did my homework :)
The atrial repolarization occurs during the QRS complex of the ECG but is obscured by the ventricle depolarization.
the ventricular depolarization, which masks the atrial repolarization wave on the electrocardiogram. This is because the QRS complex is much larger than the atrial repolarization wave and overlaps with it, making it difficult to distinguish on the ECG.

The wave indicating atrial repolarization wave is hidden by the QRS complex. Ventricular repolarization is indicated by the T wave.
The three types of deflection waves seen in a typical ECG are the P wave (atrial depolarization), the QRS complex (ventricular depolarization), and the T wave (ventricular repolarization). They represent the different electrical activities of the heart during each phase of the cardiac cycle.
P wave - represents atrial depolarization (contraction) QRS complex - ventricular depolarization T wave - ventricular repolarization (relaxation) atrial repolarization is "buried" within the QRS Complex
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
The portion of the ECG that corresponds to atrial depolarization is called the P wave. The P wave is the first wave on the ECG.
The deflection waves in an ECG tracing include the P wave (atrial depolarization), QRS complex (ventricular depolarization), and T wave (ventricular repolarization). Each of these waves represents different electrical activity of the heart during a cardiac cycle.
The portion of the ECG that indicates ventricular repolarization or recovery is the t wave. It is the wave found after the QRS complex (Ventricular depolarizaton) in a normal ECG
identify the portion of the ECG that represents the electrcal activity associated with atrial systole.
PQRST represents the five key components of a normal cardiac cycle on an ECG trace: P wave (atrial depolarization), QRS complex (ventricular depolarization), T wave (ventricular repolarization), and sometimes the U wave (late ventricular repolarization). Analyzing these waves helps to identify abnormalities in the heart's electrical activity.
