Sympatho-inhibitory response of the heart as a result of short-term acupuncture-like stimulation of the rat hindlimb is not augmented when sympathetic tone is high as a result of hypercapnia.
This study examined whether the sympatho-inhibitory response of the heart to acupuncture-like stimulation of a hindlimb in anesthetized rats depends on the sympathetic tone. Observed reductions in both cardiac sympathetic nerve activity and heart rate following short-term acupuncture-like stimulation of a hindlimb were not augmented when the sympathetic tone was high as a result of hypercapnia.
