[The oxygen supply in patients with neurocirculatory asthenia during exercise].
The working capacity and the oxygen supply during exercise were studied in 83 patients with neurocirculatory dystonia of various severity and 50 healthy subjects on the basis of the spiroergometric findings. The patients with neurocirculatory dystonia showed a decrease in such parameters of the oxygen supply during "maximum" exercise as the maximum consumption of oxygen at the threshold exercise level, the maximum oxygen pulse, the maximum pulmonary ventilation and the index of the oxygen cost per 1 kgm of work. The correlation of the disorders of the oxygen supply during exercise with the severity of the clinical course of the disease elucidated their relationship: a decrease in the maximum oxygen consumption at the threshold exercise level and an increase in the "oxygen cost" of 1 kgm of work were most pronounced in a group of patients with a severe course of the disease.
