| Abstract(in English) | The purpose of this study is to indicate that Tone-Entropy analysis has high precision to measure cardiac autonomic nervous system (CANS) activity as compared with time domain indexes, SDNN, rMSSD, pNN50, and frequency domain indexes, TP, LF, HF and LF/HF. The eighteen subjects were participated in this experiment. The subjects performed 3, 6, 10, 15 and 30 times/min, not in order, controlled breathing trials with sitting on the comfortable chair. Then, before and after the controlled breathing trials, voluntary breathing trials were also performed. Our results show that parasympathetic nervous system activities were activated during 6, 10 times/min trials and were decayed during 3 times/min trial. Against it, frequency domain indexes disagree with the interpretation of Tone-Entropy analysis. Moreover, it is concluded that Tone-Entropy analysis has more stable measure as compared with time and frequency domain indexes because SE/mean of entropy is very low SE/mean as a precision. |
