Abstract: 
In the present paper the changes of spectral parameters of heart rate variability were investigated in patients with IHD during urological operations under epidural anaesthesia. We aimed to analyze a possibility to use this method for estimation of an operational stress degree and anaesthesia adequacy. The general spectral power, and also spectral power VLF, LF, HF frequency ranges, as well as their relation were determined. By means of spectral analysis of heart rate in patients undergoing urological surgery under multicomponent epidural anaesthesia we found marked depression both of sympathetic and parasympathetic regulation of the heart rate For patients with similar surgery under a classic epidural anaesthesia an enhancement of sympathetic activity was registered during the surgery, though without marked clinical signs.
