title: Deglutition syncope associated with carotid sinus hypersensitivity.
abstract: A 78-year-old patient complained of syncope, near syncope, and dizziness when eating; complete atrioventricular block, with ventricular asystole for 3.6 seconds, was recorded on continuous electrocardiographic monitoring. Left and right carotid sinus massage produces sinus arrest and ventricular asystole lasting 6.4 and 4.8 seconds, respectively. These phenomena were prevented by atropine administration. The symptoms were completely relieved by permanent pacing, but the patient died 6 months later because of large cell undifferentiated carcinoma of the lower third of the esophagus.
