A 56-year-old woman was admitted for recurrent syn-cope. She went through subtotal gastrectomy with in-traoperative vagotomy 1 month prior. She experienced recurrent loss of consciousness for a few seconds when trying to eat or brush her tongue (video on the Neuro-logy ® Web site at www.neurology.org). Syncope in glossopharyngeal neuralgia may be caused by bradycar-dia related to the glossopharyngeal-vagal reflex.1 She had no inherent cardiac history such as an atrioventric-ular block. In our patient, denervation hypersensitivity or synkinesis of the vagus nerve by a glossopharyngeal input might be plausible mechanism. Suppression of the activation of the hypersensitized nerve by carbamazepine2 gradually decreased heart rate fluctuation and syncope. AUTHOR CONTRIBUTIONS H. Im: description of the case. H.J.
