Hen the nurse is analyzing an electrocardiogram (ECG), P Wave waveform illustrates atrial depolarization.
This is further explained below.
What is atrial depolarization?
Generally, The atrial musculature will start to contract when the atrial membrane gets depolarized.
When the atria contract, there is an increase in the pressure inside the atrial chambers.
Because of this, a greater volume of blood is forced to pass through the open atrioventricular (AV) valves, which eventually leads to a more rapid flow of blood into the ventricles of the heart.
When the nurse is looking at an electrocardiogram (ECG), the waveform that is known as a P Wave reflects atrial depolarization. This is something that the nurse will notice.
