Excerpt

The sympathetic arm of the autonomic nervous system provides homeostatic control of arterial blood pressure on a beat-by-beat resolution through the modulation of muscle sympathetic nerve activity (MSNA). An increase in MSNA α-adrenergic-mediated [ 1] peripheral vasoconstriction and a corresponding increase in arterial pressure. Signal-averaging analytical techniques have been developed [ 2] and refined [ 3] to assess sympathetic transduction following spontaneous bursts of resting MSNA. This method of quantifying the pressor responses to cardiac cycles with bursts of MSNA is an increasingly utilized outcome measure for examining sympathetic cardiovascular regulation across a variety of conditions (e.g., aerobic fitness, altitude, pregnancy). In addition, there is interest in uncovering the hemodynamic responses to cardiac cycles absent of MSNA bursts, which may provide insight into the regulation of arterial pressure during sympathetic quiescence [ 4, 5]. While advances have been made in the ability to identify bursts of MSNA [ 6] and analyze the cardio(vascular) responses to cardiac cycles with or without bursts of MSNA [ 7], further research into the methodological considerations for spontaneous sympathetic transduction to blood pressure is warranted. …
