Carotid sinus hypersensitivity, as a cause of syncope, in a patient with coronary artery disease: A case report

Bishal Dhakal et al. Ann Med Surg (Lond). .

Abstract

Introduction: Carotid sinus hypersensitivity is one of the unexplained causes of syncope in old age. There are variations in presentations of carotid sinus hypersensitivity.

Case presentation: A 56-year-old male, known case of coronary artery disease, presenting with syncope, was diagnosed as carotid sinus hypersensitivity finally. He was treated with the placement of dual chamber pacemaker.

Clinical discussion: The etiology of unexplained syncope is itself a challenging for clinicians. In the presence of a known risk factor, it is uncommon for carotid sinus hypersensitivity to be present as a cause of syncope.

Conclusions: Hence, the rare disorder like carotid sinus hypersensitivity should also be considered as a cause of syncope despite the presence of co-morbidity like coronary artery disease.

Keywords: Carotid sinus hypersensitivity; Carotid sinus massage; Carotid sinus syndrome; Orthostatic hypotension; Vasovagal syncope.
