Sinocarotid reflex

Sinocardial reflex (r. synocardicus; anat. sinus cardius carotid sinus), a reflex caused by irritation of the sinocarotid zone and manifested in a change in heart rate. The sinocardinal excitatory reflex develops when the sinocarotid nerve, located in the carotid sinus, is irritated and consists of an increase in heart rate due to a decrease in the influence of the vagus nerve on the heart. The synocardial reflex is important for maintaining a constant heart rate and ensuring adequate blood supply to the brain and other organs.

The sinocaratic reflex is a protective reflex that occurs in a person when the carotid sinus, located in the neck, near the carotid artery, is irritated. In this case, a change in heart rhythm occurs, expressed in an increase in pulse. Causes and manifestations of the Sinocardiac reflex The reflex reaction occurs under the influence of impulses coming from the carotid sinuses to the nucleus of the vagus nerve, which is located in the medulla oblongata. The most common causes of the syndrome are heart disease, damage to the arteries located in front of the neck, hemorrhages, and damage to the Nitsch vein. **Symptoms** The appearance of a reflex sinocardial reaction is usually manifested by weakness, feelings of dizziness, nausea, as well as pain in the chest, upper abdomen, and occipital part of the head. Due to changes in heart rate, a feeling of weakness may occur, as a result of which a person may lose consciousness. The manifestation and elimination of the symptoms of this reaction depend on the severity of the disease, the location of which is a foreign body or
