Sinoatrial Node

The sinoatrial node is one of the key elements in the work of the heart. It is located in the wall of the right atrium and is responsible for generating electrical impulses that are then transmitted throughout the heart.

The sinoatrial node plays an important role in the regulation of heart rhythm and ensures the stability of heart contractions. It is also responsible for synchronizing the work of the atria and ventricles of the heart, which allows for the correct sequence of contraction and relaxation of the heart muscle.

However, the sinoatrial nodes can be subject to various diseases, such as arrhythmias, blockades and other disorders. In such cases, medical attention and treatment are required.

In general, the sinoatrial node is an important element in the functioning of the heart and requires constant attention and monitoring from doctors.

The sinoatrial (SA) node is a node of the 2nd order node and connects the node of the atrium and the sinus node. It is the place where an impulse is generated to the heart muscle with a regular frequency of 60-90 beats per minute, which is carried out with the help of a node to contract the ventricles and atria. Located anteriorly along the posterior surface of the left atrioventricular valve. This node is a fast current flower and therefore causes depolarization with rotation of the node's unmyelinated dendrites into the left atrium and atrium. The clinical significance of the sinus node is determined by many factors
