The P wave of the electrocardiogram is considered as a signal from the DEPOLARIZATION of the atria in the heart. This depolarization drives the contraction of the atrial musculature.
An electrocardiogram (ECG) is a device that records the electrical activity of the heart. This record can then be used to diagnose different heart conditions.
The P waves occur when the sinoatrial node generates an action potential which is capable of depolarizing the atria.
This depolarization is then followed by atrial contraction and an increase of the pressure in the atria.
