Abstract
The influence of pharmacological autonomic nervous system interventions on nonlinear cardiovascular regulatory indices is nowadays still not clear. The present study assesses the effects of autonomic blockade (α- and β-adrenoceptor and cholinergic) on cardiovascular function by heart rate variability (HRV) and blood pressure variability (BPV) in rats using the nonlinear numerical noise titration technique. The results show that the α-adrenoceptor pathways seem to have an important contribution in the generation and control of nonlinear HR and especially BP fluctuations, while β-adrenoceptor and cholinergic interventions have a negligible contribution to the nonlinear dynamical control. 1.
