Összefoglaló. A bal oldali septalis fasciculusblokk EKG-manifesztációja a magas, keskeny R-hullám a V1–2-elvezetésekben. Egy eset kapcsán ennek frekvenciafüggő megjelenése kerül bemutatásra. A hazai szakirodalomban még nem ismert a bal oldali septalis fasciculusblokk, irodalmilag is ritka ennek frekvenciafüggő megjelenése. Orv Hetil. 2020; 161(47): 2011–2013.
Summary. Electrocardiogram with dominant R wave in the right precordial leads (V1–2) are the most important ECG manifestations of left septal fascicular block. A case is presented with acceleration-dependent left septal fascicular block. Its a rare manifestation of the tetrafascicular conduction system, not published in the Hungarian medical records.
