title: Carotid sinus syndrome associated with carcinoma of the pyriform fossa.
abstract: A patient who developed syncope due to carotid sinus syndrome is described. The patient was suffering from carcinoma of the pyriform fossa for the past one year and received radiotherapy in the region of the neck for the same. Demand pacing was ineffective in alleviating syncopal episodes. The patient responded to oral administration of an anticholinergic (belladonna) and a sympathomimectic agent (orciprenaline).
