[Methodological aspects of determining the functional condition of the vegetative nervous systems in patients in medicine].

Described in the paper is a combined method of estimating the functional condition of the autonomous nervous system, which makes it possible to assess the original condition, the level of functioning in response to the load and the results of the activity of the autonomous nervous system targeted at maintaining the homeostasis. The integrated estimation of a functional state of the autonomous nervous system in a clinic provides for obtaining the detailed information on the state of patients and can be applied in clinical practice to evaluate objectively the patients' condition.
