Abstract
The authors analyzed changes in spectral parameters of heart rhythm variability during active orthostatic test in patients with vasovagal syncope, residing in Novokuznetsk city. Findings are that industrial city inhabitants even in yough age present disorders of sympathic vasomotor regulation, that manifest in orthostasis with decreased parameter of low frequency variations more than by 50% of initial value Relative sympathetic dominance is supported by more marked increased of parasympathetic activity (power of high-frequency variations is decreased more than by 80%). Decrease in tonic vagal influence enables to increase chronotropic heart function. Orthostatic tachycardia appears in increased power of very low frequency variations during the test — that proves increased serum catecholamines level. Thus, spectral analysis of heart rhythm variability is effective in finding the cause of orthostatic disorder.
