The aim of our work is to study the peculiarities of vegetative regulation of heart in patients with systemic scleroderma. When studying the indexes of spectral and time analyses in the general group of patients with systemic scleroderma the total spectrum power was lower than normal values, mainly owing to parasympathetic component decrease. Low cardiac rhythm variability was noted in 66.1% of patients with systemic scleroderma, in 20.5% of them it being greatly lowered. During the conduction of active orthostatic sample, the reactivity of parasympathetic and activation of sympathetic part of vegetative nervous system appeared to be simultaneously lowered in 25 (42.3%) examined patients. 6.77% patients with systemic scleroderma that can be attributed to risk group as pernicious arrhythmia development.

Keywords:systemic scleroderma, cardiac rhythm variability, vegetative nervous system.
