[Assessment of adequacy of analgesia with spectral analysis of sinus rhythm variability in the maintenance of anesthesia].
A spectral analysis of the sinus rhythm (5-minute groups of cardiointervals) was made in 32 patients during anesthesia by the method of a fast Fourier transform with the estimation of the spectral density in 3 conventional ranges (HF, LF, VLF). Its indices were shown to depend on the stages of anesthesiological maintenance and operative intervention.
