What is the carotid sinus?

Carotid sinus is a slightly enlarged area in the carotid artery where it is divided into internal and external carotids. It contains sensitive areas called baroreceptors. These birroreceptors respond to pressure and, if stimulated, can cause reduced blood pressure, vasodilation and may slow down the heart rhythm. There are two carotid arteries, one on each side of the body. As divided into internal and outer carotid arteries, sinus carotid arteries have formed where the division occurs. If blood pressure increases, the pressure in the sinus also increases, and the birds react by dilatation by a blood vessel by a process called vasodilation. The spread of blood vessels leads to a reduction in blood pressure. Below the normal custody process helps keep blood pressure at the right level.

In some people, there is a disorder called carotide sinus syndrome or hypersensitivity to carotid sinus. In this state, baroreceptors become oversensitive to pressure and create an exaggerated reaction in the carotid of sinus reflex. In some cases, even a slight pressure on the neck, such as turning the head or wear a shirt with a tight collar, can cause symptoms. The pressure on the neck leads to a rapid drop in blood pressure, dizziness and even fainting, as biroreceptors cause blood pressure to reduce, leading to a reduction in blood flow to the brain. This condition rarely occurs in individuals under 50 and is more common in men than in women.

Carotide sinus syndrome can be diagnosed with carotid sinus massage. This process is a place where this part of the artery is manually stimulated under the controlled, hello of the monitored Ghla. By observing and recording how the patient's blood pressure and other symptoms change during stimulation, physicians may determine the severity of the condition. Sinus carotid hypersensitivity is caused by physical irregularity in the sinus structure, but doctors have not yet precisely determined how and where this malformation occurs.

Treatment of this condition with foxand. Some cases are treated by simply avoiding pressure on the front of the neck, while others require dietary treatment such as avoidance of caffeine and other stimulants. Medicines can help alleviate the condition. Particularly serious cases could require a pacemaker.
