Autonomous Nervous System (ANS) and Possible Determination of ANS Activity in Obesity
Autonómny nervový systém (ANS) a možnosti stanovovania aktivity ANS pri obezite
Obezita je jednou z chorôb, pri ktorej sa predpokladá zmenená aktivita autonómneho nervového systému a jeho jednotlivých subsystémov – sympatika a parasympatika. Pri hodnotení aktivity jednotlivých zložiek ANS pri obezite vo väčšine prác je častým nálezom zníženie parasympatikovej aktivity, kým závery hodnotenia sympatikovej časti sú rozporuplné.
Na zisťovanie interakcie sympatika a parasympatika sa v súčasnosti používajú hlavne časová a spektrálna analýza variability frekvencie akcie srdca, resp. tlaku krvi, či používanie kardiovaskulárnych testov. Neustále zvyšujúci sa nárast výskytu obezity núti pokračovať v štúdiu zmien aktivity ANS, jej mechanizmov, ako aj hľadať nové a neinvazívne spôsoby stanovovania týchto zmien pri obezite.

Overview
Obesity belongs to diseases with presumably modify activity of autonomous nervous system and its individual sympathetic and parasympathetic subsystems. The evaluation of individual components of ANS in obesity in most papers is characterized by the frequent finding of decreased parasympathetic activity, whereas the conclusions related to sympathetic part are controversial.
The determination of interactions between sympathetic and parasympathetic subsystems is presently analyzed mainly by time and spectral analysis of variability in the frequency of heart action, blood pressure or cardiovascular tests. The continual increase in the occurrence of obesity indicates how important it is to investigate changes in ANS activity, its mechanisms as well as to search for new and noninvasive mode of determination of these changes in obesity.
