内容記述(抄録等)The aim of the present study was to find the reference values for autonomic nervous function tests and to find out whether breathing pattern has influences on heart rate variation.The male healthy subjects with mean (standard deviation) of age 58.8 (4.2) years were studied.The heart rate variation was measured by electrocardiograph measurement during both spontaneous, a Fast Fourier Transformation program was used.We used two divisions of the total frequency area.in the I-division, the total frepuency band with the area from 0.15 to 0.40Hz and in the Ⅱ-division, into low frequency ban with the area from 0.04 to 0.12Hz and high frequency band with the area from 0.20 to 0.28Hz. Frequency related power of the bands was calculated.Frequency related power significantly increased during deep breathing.During both spontaneous and deep breathing there ware strong gatherings of power between the frequencies 0.15 and 0.20Hz and between the frequencies 0.29 and 0.40Hz, which were not calcurated in the Ⅱ-division.our results suggest that breathing pattern has an influence on neart rate variation in supine position which must be considered in the evaluation of autonomic neuropathy based on heart rate variation.We assume that the I-division of the total frequency area is more infomative in the evaluatuin of cardiac autonomic function during different autonomic sontexts.
