Abstract
We herein report a case of suspected cough syncope, in which the patient repeatedly experienced coughing (usually when drinking a liquid), resulting in a loss of consciousness or syncope. An endoscopic examination of the pharynx and larynx showed poor swallowing, and aspiration was detected by fluorography using iotrolan as a contrast agent. However, aspiration was not detected when barium, which has high viscosity, was used as the contrast agent. We believe that aspiration due to the swallowing problem may have triggered the coughing,resulting in syncope. The patient underwent swallowing rehabilitation and was advised to avoid some types of fluids,which resulted in an improved condition, including a decrease in the coughing and syncope attacks.
