In a study of 45 cases of ventricular pre-excitation, 19 were classified as type A and 20 as type B according to Rosenbaum's criteria, which depend on the polarity of the major deflections in the right praecordial leads and not, as is commonly thought, on the direction of the delta vector. Six cases that could not be classified as type A or type B were termed intermediate. Vectorcardiograms were recorded from 29, and these showed a wide but continuous range of values for both the delta and the main QRS vectors in all three planes. Any classification based on these features must, therefore, depend on arbitrary quantitative data. Three patients in this series had associated right bundle-branch block. A review of the published reports on the association of pre-excitation and bundle-branch block failed to provide a rational basis for the classification of pre-excitation. It is emphasized that Rosenbaum's classification is empirical and its validity is questioned.
在一项对45例心室预激患者的研究中，根据罗森鲍姆标准，19例被归类为A型，20例为B型。该标准取决于右胸前导联主波的极性，而不是像通常认为的那样取决于δ向量的方向。6例无法归类为A型或B型的病例被称为中间型。对29例患者记录了向量心电图，结果显示在所有三个平面中，δ向量和主要QRS向量的值范围广泛但连续。因此，基于这些特征的任何分类都必须依赖于任意的定量数据。该系列中有3例患者合并右束支传导阻滞。对已发表的关于预激与束支传导阻滞关联的报告进行回顾，未能为预激的分类提供合理依据。需要强调的是，罗森鲍姆分类是经验性的，其有效性受到质疑。
