The characteristic wave patterns of a typical right bundle branch block as seen in an ECG. Only the precordial lead V1 and V6 are shown. Wide QRS complexes are present and there's T wave inversion in lead V1 which is normal in this condition. Note the typical wide and deep s wave in V6. The small q wave in V6 may not always be present. Below each QRS complex is its designation (<i>rSR</i> and <i>qRs</i>) according to nomenclature.
