Abstract

In a recent very interesting report of a case of terminal heart-block, Pardee1 demonstrates that an extensive anatomical lesion of the auriculoventricular bundle may be present without disturbance of its function. He then gives three lists : (1) ten cases, in which complete destruction of a transverse section of the bundle was invariably accompanied by complete heart-block; (2) six cases,2 with varying degree of block, in which no lesion of the bundle existed; (3) ten cases, (six of complete and four of partial heart-block) accompanied by very slight pathological changes. The intermediate degrees of bundle involvement he has not considered. That is, though it has been firmly established that lesions of the conductive system may cause partial and complete heart-block, it seems also true that such lesions may exist (even though of considerable extent) without block; and further that partial or complete block may exist without
