Carotid sinus hypersensitivity: disease state or clinical sign of ageing? Insights from a controlled study of autonomic function in symptomatic and asymptomatic subjects

Abstract

This study has demonstrated an association between CSH with increased resting sympathetic activity and baroreflex sensitivity regardless of the presence of symptoms, indicating the presence of autonomic dysregulation in individuals with CSH. Our findings therefore suggest that CSH is part of a generalized autonomic disorder but do not differentiate between asymptomatic and symptomatic individuals.
