The frequency domain components of HRV including VLF (A), LF (B), and HF (C) during 30 min of Nadir-1 phase in the Sham (N = 5), Vag (N = 5), SHS (N = 7), and Vag + SHS (N = 8) groups. VLF, LF, and HF were expressed as a log scale of ms2. Data are mean ± SE. The comparison between groups was performed by analysis of variance ANOVA. #P < 0.05, versus the Sham group; aP < 0.05, versus the Vag group; bP < 0.05, versus the SHS group
