Abstract

At 4 healthy volunteers in age from 22 to 29 years (2 men and 2 women) with the body mass index from 21 to 23 kg/m2the comparison of different methods of optimal frequencies of paced breathing detection, at which the greatest approximation to the optimum ratio of spectral indices of heart rate variability (HRV) was achieved were studied. Detection of optimal frequency was performed by enumeration of breathing frequency (BF) – increase and decrease from 6 to 12 breaths per minute and back, and by using automatic algorithm. The results showed the coincidence of optima obtained by stepwise increasing and decreasing of BF with data from automatic search, that indicates the possibility of method algorithmization and sufficiently high accuracy and reliability of the proposed algorithm.
