A 63-year-old man complained of cough syncope for 15 days. During vigorous coughing, he lost consciousness for a few seconds. He had past medical history of bronchial asthma and diabetes mellitus. Various tests for syncope including electroencephalogram, electrocardiogram, 24-hours Holter monitoring, echocardiogram, carotid sinus massage, tilt table test, carotid duplex, and brain MRI were normal.
