Low frequency component of the systolic arterial pressure variability of heart failure treated with intracerebroventricular (ICV) infusion of vehicle (HF-VEH), or with ICV imfusion of angiotensin II type 1 receptor blocker (HF-ARB), or with ICV infusion of nuclear factor erythroid 2-related factor 2 activator, tert-butylhydroquinone (HF-tBHQ), or sham treated with ICV infusion of VEH, or with ICV infusion of ARB, or with ICV infusion of tBHQ. n = 5 for each group. All data are shown in dot plot and mean ± standard deviation. * p < 0.05 vs. HF-VEH in HF-ARB and HF-tBHQ. +
p < 0.05 vs. HF-ARB in HF-tBHQ.
