Diagnostic Considerations

Important considerations

Performing carotid sinus massage on a patient with cerebrovascular disease or carotid bruit on auscultation may precipitate neurologic manifestations.

Patients with severe symptoms attributed to CSH should be advised against driving vehicles until the condition is addressed by a physician.

Other conditions to consider in patients with carotid hypersensitivity include the following:

  • Vasovagal syncope

  • Orthostatic hypotension

  • Situational syncope (eg, associated with cough, deglutition, micturition, defecation)

  • Cardiogenic syncope
