      We prospectively evaluated 46 patients who had intrahisian conduction delay. Twenty-three had a split His potential and 23 had a prolonged HV interval with a normal QRS complex.

      In this issue of HeartRhythm is a very interesting article by Ragupathi et al, who describe the natural history of patients with putative intrahisian atrioventricular (AV) block. The authors have nicely shown that although these patients often present with traumatic and very worrisome syncopal episodes, they seem to have a very low incidence of progression to complete AV block.
