title: Retrograde Concealed Conduction in the His-Purkinje System.
abstract: An 83-year-old man was seen due to recurrent syncopal episodes. Only the His bundle recording was able to be obtained, which showed the His-Purkinje System as the site of a conduction delay. A permanent dual-chamber pacemaker was implanted with no further syncopal episodes.
