Abstract: 15 patients with polysomnographically verificated syndrome of obstructive apnoea in sleep (apnoea index value was equal to 35.6) were examined. The peculiarities of cardiac rhythm vegetative regulation were investigated with the help of cardiorhythmintervalography technique. The decrease of amplitude of the middle frequency peak (the slow waves of the first order, SW1) as well as the predomination of the low frequency peak (slow waves of the second order, SW2) were observed in cardiac rhythm spectrum. These findings reflected the insufficiency in sympathetic-adrenal mechanisms of regulation. Besides, unlike the healthy individuals SW2 peak in patients exceeded significantly respiratory waves peak. The last observation combined with the weak influence of respiratory waves on the total rhythm dispersion was estimated as the initial parasympathetic regulation insufficiency manifestation.
