Different hypothesis of origin of slow waves (Wfand VhF) registrated at spectral analysis are discussed. The importance of taking into consideration the methodical approaches used at spectral analysis is underlined. The attempt of correlating the generators of LF and VLF waves with different parts of the vegetative nervous system is done. The analysis findings obtained from the students, quiescent and in examination stress condition have revealed close correlation of absolute power between waves and parameters of variability of cardiac rhythm, referring to the activity of Parasympathical nervous system. The supposition that at an emotional stress, there is an attenuation of controlling effect on heart on the part of overlying departments of the central nervous system is put forward.сердечный ритммедленные волныспектральный анализ1.Баевский Р.М., Кириллов О.И., Клецкин С.З.
