Atrial systole

Atrial systole is the contraction of the atria myocardium and the release of blood from them into the ventricles of the heart. This process occurs as a result of electrical impulses that are generated in the cells of the atria.

Atrial systole begins when an electrical impulse occurs in the cells of the atria, which spreads throughout the entire tissue of the atria. This impulse causes the atria to contract, causing blood to be pumped out of them.

When atrial systole ends, the atria relax and ventricular systole begins. The ventricles contract and pump blood into the aorta and pulmonary artery.

The importance of atrial systole is that it ensures a continuous flow of blood into the ventricles and maintains the functioning of the heart. If atrial systole is impaired, it can lead to various heart diseases such as arrhythmia and heart failure.

In order to prevent disruption of atrial systole, it is necessary to monitor your health and lifestyle. Regular exercise, a healthy diet, and avoiding bad habits can help keep your heart healthy and prevent disease. It is also important to get regular medical checkups and see a doctor if you experience any heart-related symptoms.
