A 74-year-old male presented with history of recurrent syncope and fall that once caused scalp-injury. The episodes were sudden and lacked any prodrome. He regained consciousness spontaneously. Clinical examination was unremarkable, and there was no neck vessel bruits or carotid sinus hypersensitivity. There was no postural hypotension and the Tilt-table-test was negative. His Electrocardiogram showed right bundle branch block and a normal PR and corrected QT intervals (Panel A). His neurological evaluation including magnetic resonance imaging of the brain and cerebral vessels was normal.
