| Abstract: | This report describes an otherwise healthy young woman who presented with syncope during episodes of advanced atriovenlricular (A V) block. The His bundle recordings during normal sinus rhythm and atrial and ventricular pacing were normal. Carotid sinus massage produced no abnormality. Subsequently, (he patient received a permanent pacemaker and has been free of symptoms. In termittent advanced A V block has been observed on follow-up electrocardiograms. This unique case demonstrates a potential limitation of routine electrophysiologic investigation. |
