title: [Pronounced anterior displacement--a newly defined intraventricular heart conduction disorder].
abstract: A pronounced anterior displacement in the VCG which was not evoked by a posterior infarction or a right-ventricular hypertrophy has its cause in a circumscribed disturbance of the conduction of the septal or medial fascicle of the left Tawara-branch of the conduction system of the heart. On the basis of personal observations of this new defined disturbance of the conduction system the parameters for the recognition in the 12 conventional leads of the ECG are demonstrated. Such a pronounced anterior displacement may be supposed in Rv2 greater than 1 m V and Rv2/Sv2 greater than or equal to 1.2. The analysis of an additional 57 VCG with left anterior hemiblock yields in 6 the additional proof of an amphysized anterior orientation. This shows that the group of the left-anterior hemiblocks is not unique and pleads for the enlargement of Rosenbaum's conception of the conduction system in the sense of a functional division into three parts of the left Tawara-branch.
