Carotid Sinus Hypersensibility: A Concept on the Way

Abstract

This review examines the pathogenesis of Carotid Sinus Hypersensitivity (CSH) by describing the different hypotheses that exist in literature. One hypothesis is that CSH is not a disease of the heart but of the central and/or peripheral nervous system where the heart is the victim. CSH is associated with cognitive disturbance, vasovagal syncope and orthostatic hypotension. Another hypothesis is that the CSH is considered a syndrome or a symptom associated with different diseases so as to require a diagnostic framework. This Hypothesis is the basis of frequent recurrences that are associated with the pacemaker implant therapy only.
