Learning Issue: Carotid pulse and vagal stimulation ( to not just make a crap LI, I found a condition called related to carotid sinus hypersensitivity) · Don’t Miss This: See how to perform palpation to not provoke vagal stimulation · Definition: Carotid sinus hypersensitivity (CSH) is an exaggerated response to carotid sinus baroreceptor stimulation. It results in dizziness or syncope from transient diminished cerebral perfusion. · Causes: Although baroreceptor function usually diminishes with age, some people experience hypersensitive carotid baroreflexes. For these individuals, even mild stimulation to the neck results in marked bradycardia and drop in blood pressure. · Risk Factors or Predisposing Factors: Patients can be predisposed to carotid sinus hypersensitivity if they are of male sex, advanced age, have hypertension, coronary artery disease, orthostatic hypotension, vasovagal syncope, alzheimer disease, parkinson disease, dementia with Lewy body, concurrent medication with digitalis, beta-blockers, and methyldopa
