A large P wave on an ECG typically indicates an abnormality in the electrical activity of the atria of the heart. This could be due to conditions such as atrial enlargement, atrial fibrillation, or other atrial arrhythmias. Further evaluation by a healthcare provider may be needed to determine the underlying cause.
I believe it is the P Wave. A good way to remember is all of the Waves are in alphabetical order. P Wave, Q-R-S Waves and the T Wave
The P Wave on and ECG shows depolarization of the Atria, and the characteristics should be smooth, round, no more than 2.5 mm in height, no more than .11 seconds in duration, and positive in leads I,II, aVF, and V2 through V6.
P wave forms reflect atrial depolarization in the heart, specifically the spread of electrical activity through the atria causing them to contract. This is the initial wave seen on an electrocardiogram (ECG) tracing.
An absence of P wave in an ECG may indicate atrial fibrillation, a condition where the atria of the heart quiver instead of contracting effectively. This can lead to irregular and fast heart rhythms. Further evaluation by a healthcare provider is necessary to determine the underlying cause and appropriate management.
The electrical milestone event that occurs at the P wave of the cardiac cycle of the EKG is atrial depolarization. The upward stroke is right atrial depolarization, and the downward stroke is left atrial depolarization. Normally, this lasts for no more than 0.11 sec.
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 P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
The next wave after the T wave in an ECG is the P wave, which represents atrial depolarization.
P waves represent the atrial depolarization. QRS complex represent the ventricular depolarization. T waves represent the ventricular repolarization.
P, Q, R, S and T each represent a wave of the electrocardiogram (ECG). The waves, and the ECG in general, confer a graphic representation of the hearth's electric activity. The ECG of a healthy person usually contains three waves, called the P wave, the QRS complex and the T wave. The P wave corresponds to the electric depolarization of the auricles, the QRS complex corresponds to the electric depolarization of the ventricles and the repolarization of the auricles, and the T wave corresponds to the electric repolarization of the ventricles. A complete period of an ECG (that is, the P, QRS, and T waves) represents the electrical activity of the heart for one pulse.

The P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing in an ECG.
P wave
The key differences between the P wave and T wave in an electrocardiogram (ECG) are that the P wave represents the electrical activity of the atria contracting, while the T wave represents the electrical activity of the ventricles relaxing.
ECG records electrical activity and not mechanical, hence it has nothing to do with contraction. But P wave represents atrial depolarization.
