May indicate size-selective baroreflex regulation of sympathetic outflow; hypothesis-generating for autonomic mechanisms in cardiovascular disease.
Observational (n=15)
p-value: p=<0.05
Small-medium sized action potentials within muscle sympathetic nerve activity bursts are governed by baroreflex mechanisms, whereas large action potentials are only weakly associated with baroreflex control.
Salmanpour et al. (2012) conducted an observational in Healthy (n=15). Arterial baroreflex control was evaluated on Relationship between burst probability and diastolic blood pressure (p=<0.05). Arterial baroreflex control strongly regulates the occurrence of small-medium sized action potentials within sympathetic bursts, but has weak control over large action potentials.
