title: [An analysis of the autonomic manifestations of Raynaud's phenomenon by the spectrum of heart rhythm variability].
abstract: A study was made of the specificity of segmental and suprasegmental vegetative disorders seen in patients with Raynaud's phenomenon (RP). The sympathetic-parasympathetic interrelations were estimated according to the dynamics of the spectral constituents of heart rhythm under different functional conditions. There was a decrease of the sympathetic activity modulated by the stem and segmental mechanisms, accompanied by activation and rigidity of the suprasegmental ergotropic systems, leading to a stable vasospasm on the periphery. This may determine the low efficacy of vegetotropic peripheral drugs and a higher therapeutic effect of psychotropic drugs which reduce ergotropic activation.
