Carotid sinus syndrome
- Description: a type of recurrent reflex syncope that primarily occurs in individuals with carotid sinus hypersensitivity when pressure is applied to the carotid sinus
- Mechanism: increased carotid sinus sensitivity (due to, e.g., increased baroreceptor or peripheral receptor response)
- Risk factors: coronary atherosclerosis, previous history of neck surgery or irradiation, age (> 50 years)
- Trigger: pressure on the carotid sinuses (e.g., during a massage, when shaving, tightening a necktie)
