Fig. 3From: Heart rate variability and pulmonary dysfunction in rats subjected to hemorrhagic shockThe frequency domain components of HRV including VLF (a), LF (b), HF (c) and LF/HF ratio (d) in the Sham (n = 5), Vag (n = 5), HS (n = 7) and Vag + HS (n = 7) groups. Data are mean ± SE. *P < 0.05 vs. the baseline; #p < 0.05 vs. the Sham group; ap < 0.05 vs. the Vag group; bp < 0.05 vs. the HS groupBack to article page
