TEMPORARY FLUCTUATIONS OF HEART RATE VARIABILITY SPECTRAL INDICES IN HEALTHY VOLUNTEERS DURING PACED BREATHING
Keywords:
heart rate variability, fast Fourier transform, human physiologyAbstract
In 20 healthy volunteers aged from 19 to 30 years (7 men and 13 women) the patterns of temporary fluctuations of total power of spectral indicators (TP, VLF, LF and HF) heart rate variability (HRV) using a one-minute buffer during paced breathing (respiratory rate – 12 per minute) were studied. It was found that temporary fluctuations of total power of HRV spectral indices in healthy volunteers during paced breathing are slow waves in frequency range 0,05-0,07 Hz and are similar to each other qualitatively and quantitatively. Nature of these fluctuations allows to associate them primarily with metabolic reactions of the organism.
