Non-invasive measurement of baroreflex during Valsalva maneuver: Evaluation of alpha and beta-adrenergic components

Highlights • Measurements of adrenergic baroreflex sensitivity (BRSa) obtained during the Valsalva maneuver can improve the clinical assessment of dysautonomia. • Separate analysis of the alpha- and beta-adrenergic components of the BRSa resulted in greater reliability compared to pre-existing metho...

Description
Summary:Highlights • Measurements of adrenergic baroreflex sensitivity (BRSa) obtained during the Valsalva maneuver can improve the clinical assessment of dysautonomia. • Separate analysis of the alpha- and beta-adrenergic components of the BRSa resulted in greater reliability compared to pre-existing methods. • New BRSa measurements may help differentiate normal physiologic variants from mild dysautonomia.
