The rate of the ventricle is, however, more rapid thanthe usual automatic rhythm. One might ask whether this were, perhaps,one of those instances described by Erlanger and Blackman^ of rela-tively complete block, where an automatic ventricular rhythm has arisenm a heart in which the auriculoventricular bundle is still capable oftransmitting some stimuli. These stimuli are, however, usually of sub-minimal strength and incapable, ordinarily, of interfering with the estab-lished ventricular rhythm. It is not uninteresting, however, that thesecond, fifth and eighth ventricular l)eats following the preceding auric- 5.
