Peculiarities of heart rate variability in patients having arterial hypertension with structural signs of hyperetensive encephalopathy

The aim of this study was to test the hypothesis that sympathetic hyperactivity may be conducive to early brain damages in hypertensive patients. We examined 49 asymptomatic, non-complicated essential hypertensives aged from 26 to 57 years. Positive correlation between the parameters describing sympathetic activation depth of PVH and between the parameters describing sympathetic activation and linear sizes of subarachnoidal space was revealed. Our results showed that degree and depth of LA correlated with high sympathetic and low parasympathetic tone. Correlation between sympathetic hyperactivation and liquorodynamics disturbances was revealed too.
