Fluctuations in time-domain of heart rate variability spectral indices in healthy volunteers

Abstract (resume)

In 20 healthy volunteers aged from 19 to 30 years (7 men and 13 women) the patternsof fluctuations in time-domain of total power of heart rate variability (HRV) spectral indicators (TP, VLF, LF and HF) heart rate variability (HRV) using a one-minute buffer during spontaneous breathing were studied. It was found that temporary fluctuations of total power of HRV spectral indices in healthy volunteers are slow waves with frequency of 0, 05–0, 07 Hz. These fluctuations qualitatively and quantitatively are similar to each other. Their nature allows to associate them primarily with metabolic reactions of the organism.
