Change in HRV, SBPV and BRG in High-Salt DAHL/SS. Change in HRV, SBPV and mean BRG in high salt DAHL/SS after Aβ (n = 5) or saline (n = 3) infusion. There were no significant effects of Aβ infusion on the (a) VLF (F2,148 = 0.120, ns) and (b) LF (F2,148 = 2.507, ns) components of HRV. There was a significant effect of Aβ infusion on (c) HF (F2,148 = 10.64, p < 0.0001). There was a significant effect of Aβ infusion on (d) VLF (F2,148 = 17.46, p < 0.0001), (e) LF (F2,148 = 15.59, p < 0.0001), and (f) HF (F2,148 = 17.46, p < 0.0005) components of SBPV. There was a significant difference in the change in mean BRG (Mn.BRG) (g) positive (F2,202 = 28.91, p < 0.0001) and (h) negative (F2,202 = 4.761, p < 0.001) ramps during Aβ compared with saline infusion. Data are presented as daily group means, with lines of best-fit (solid) and 95% CI (dotted). A combined best-fit line is shown for both infusion groups when the H0 was accepted (a–b). Separate lines for Aβ- and saline- infusion groups are shown when the H0 was rejected (c–h).
