The possibility of identifying the site of block by analysing the surface ECG was studied in 124 patients with 2nd or 3rd degree AV-block. In all cases His-bundle-electrography was performed. With regard to the QRS-duration (both in conducted and in escape beats) and to functional peculiarities of the AV-conduction or of the automatic centres in patients with narrow QRS complexes nearly all cases with the prognostically less favourable His-Purkinje-block are discernible.
