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.

<h3>What is Y chromosome analysis?</h3>
The Y Chromosome test is mostly used to determine if there is a paternal relationship between two males. It is an extremely accurate and conclusive test and can be used in different situations. Any two males who are connected by a direct line can have this test done in order to determine relationship.
With this information, we can conclude that Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins.
