For a 25 yo male with history of post micturation syncope -- fainted in the theatre bathroom shortly during or after urinating on a full bladder (tried to hold in his urine while watching a movie). What further evaluation will he need? There is no history of other syncopal episodes except in college once due to sleep deprivation involving fraternity hazing. He is otherwise healthy except new onset of feeling intermittent episodes of light headedness and palpitations. He was seen in the emergency room with a normal ekg, normal labs, and an incidental finding of a corpus callosum lipoma which was felt to be a developmental anomalie.
