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.
心电图向量图（VCG）中出现明显的前向移位，若不是由后壁梗死或右心室肥厚引起，则其原因在于心脏传导系统左束支的间隔或内侧束传导出现局限性障碍。基于对这种新定义的传导系统障碍的个人观察，展示了在常规12导联心电图中进行识别的参数。当Rv2大于1mV且Rv2/Sv2大于或等于1.2时，可能会出现如此明显的前向移位。对另外57例左前分支阻滞的VCG进行分析，其中6例进一步证实了前向方位的增强。这表明左前分支阻滞组并非单一情况，支持从功能上将左束支分为三个部分的角度扩大罗森鲍姆对传导系统的概念。
