Vegetative-vascular dystonia (VVD) is a complex set of symptomatic clinical symptoms that affect different organs and systems. Disease develops due to disturbances in the Central and / or peripheral zones of the nervous system.
Medicine knows many types IRR, but divided pathology on three types of vegetative-vascular dystonia say the reaction of the cardiovascular system, which differ in such kinds:
In the process of functioning of the nervous system take part two areas: the sympathetic and the parasympathetic. The first area is responsible for the load of any kind (physical, emotional, mental, psychological, heart rhythms and reduction) during wakefulness. The second is responsible for the relaxation during sleep. It turns out that in normal when two alternate system, regulating body processes zatrachivaniya and recuperation.
In case of violation of the balance of these forces is observed IRR. When there are failures in the sympathetic nervous system, the patient occurring disorders palpitations, the feeling of fear, he loses sleep and the body wears out quickly. Parasympathetic region does not provide a full recuperation, so developing hypertensive type.
The predominance of parasympathetic region functioning of the nervous system, found the opposite effect: the body is on the contrary full of energy, you can't spend. There hypotonia, depression and develops hypotonic vegeto-vascular dystonia.
In the mixed type of the disease appears to conflict between the two areas of the nervous system, in the form of the struggle for control of its activities. Patients in this case complain about the disruption of the heart, the feeling of lack of air, disorders of cardiac rhythm.
In its pure form, all three types of vegetative-vascular dystonia are rare. Often have combinations of options pathology: mixed-hypertensive and mixed-hypotonic type IRR.
