The P wave on ECG corresponds to electrical depolarization of the atria. It should be positive in lead II and negative in aVR when the P wave originates in the sinoatrial node.
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.

Contraction of both atria
The P wave represents atrial depolarization, the QRS complex represents ventricular depolarization, and the T wave represents ventricular repolarization in an electrocardiogram (ECG).
The largest wave in an electrocardiogram is typically the R wave.
The typical amplitude of a P wave on an electrocardiogram (ECG) is usually less than 0.25 mV (2.5 mm).
Special training is required for interpretation of the electrocardiogram. To summarize in the simplest manner the features used in interpretations, the P wave of the electrocardiogram is associated with the contraction of the atria
The P wave refers to the electrocardiographic representation of electrical activation of the atrial myocardium. It can be measured using an electrocardiogram.
The interaction between the P wave and T wave in an electrocardiogram is significant because it helps to assess the electrical activity of the heart. The P wave represents the electrical activity of the atria, while the T wave represents the electrical activity of the ventricles. By analyzing the relationship between these two waves, healthcare providers can identify abnormalities in the heart's rhythm and function.
A P wave denotes atrial depolarization or when your atriacontracts. It is generated by the Sinoatrial (SA) node which is the primary pacemaker and signifies a Sinus Rhythm.
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.
The P wave of a normal electrocardiogram represents the depolarization of the atria, which leads to atrial contraction. It is the first upward deflection seen on the ECG tracing and typically precedes the QRS complex. Abnormalities in the P wave can indicate conditions such as atrial enlargement or abnormal conduction pathways in the heart.
