Changes of integrated spectral density of blood pressure between 0.002 and 0.003 Hz induced by ACE inhibition

Group	ΔSpectral density (dB)
Control (n = 7)	−0.11 ± 1.47
Ganglionic blockade (n = 7)	+1.60 ± 0.96
Low-sodium diet (n = 7)	+0.29 ± 1.20
Ang II infusion (n = 7)	+0.03 ± 0.77

Relative changes of spectral density induced by ACE inhibition. Means ±s.e.m. for experiments under normal conditions (Control), and after ganglionic blockade, low-sodium diet and Ang II infusion. n, number of dogs. None of the changes was significantly different from 0 dB.
