Abstract

Abstract A lesion of a branch of the bundle of His is not as rare as is commonly supposed. It is one of the heart defects that can only be detected by means of electrocardiographic records, and because these are often difficult to secure a great many of these cases are unrecognized. One who has the opportunity of studying large numbers of heart defects with the aid of electrocardiograms is able to make this diagnosis at fairly frequent intervals. The facts presented in this paper are based on a study of twenty-five cases seen in the last six years. For this purpose only those cases which show curves that are generally accepted as typical of this lesion have been selected, the cases showing graphic records of a less characteristic type will not be considered at the present time. The following criteria have been used in selecting curves which are included in References 1. Eppinger and Rothberger: Ueber die Folgen Durchschneidung der Tawaraschen Schenkel des Reizleitungssystems , Ztschr. f. klin. Med. 70:1, 1910. 2.
