Fifty patients with diabetes mellitus were consecutively selected from the outpatient clinic. A hundred of beats of the heart at rest were recorded from each patient and power spectra of beat-to-beat variations were computed by the method of maximum entropy method (Memcalc). A definite peak of power spectral density (HF) was noted in the high frequency range from 0.15 to 0.4 Hz and so was a low and broad peak (LF) in the low frequency range from 0.04 to 0.15 Hz. However, the lower end of the LF was ambiguously overlapped by the slope of the peak (VLF) in the very low frequency range below 0.04 Hz. In patients with advanced diabetic neuropathies both HF and LF peaks were disappeared and the VLF peak was greatly reduced in height, suggesting that the VLF is also depended on the integrity of the autonomic nervous system as are the HF and the LF., 6, KJ00004311149}, pages = {49--54}, title = {自律神経機能検査としての心拍変動のパワースペクトル分析 : 平均化スペクトルによる検討.}, volume = {8}, year = {1999}, yomi = {ウチカワ, トオル} }
