“…The selectivity of bundle-branch fibrosis for the conduction system was clearly recognized by Aschoff (1910), but the pathogenesis of such lesions remains controversial. Yater, Cornell, and Claytor (1936) regarded the lesions as anoxic, but failed to explain the sparing of adjacent myocardium. James (1967) has described various types of small vessel disease in conduction disturbances but such changes are not seen in bundle-branch fibrosis.…”

“…Elektrokardiographisch ist diese Form durch die Kombination des überdrehten Linkstyps und eines Rechtsschenkelblocks zu erkennen (5, 38, 51, 53). Dieses im Elektrokardiogramm relativ häufige Syndrom wird auch als »bilateraler« Schenkelblock bezeichnet (9,21,23,30,43,56). Die Diagnose kann aus den Extremitätenableitungen vermutet und durch zusätzliche simultane rechtspräkordiale Ableitungen gesichert werden.…”

“…They also postulated that in complete block, if the ventricular complexes were of an aberrant type, bilateral bundle-branch block must exist, whereas if the ventricular complexes were of normal contour the interruption must have been above the bifurcation. Yater, Cornell, and Claytor in 1936 published a review of the published reports of 48 patients with pathologically proven complete A-V block due to bilateral bundle-branch block. On the basis of their studies, they concluded that a large number of patients with complete A-V block would have an interruption of both bundle-branches rather than a block above the bifurcation.…”

“…However, two pacemakers acting simultaneously is a very remote possibility and this could only occur by pure chance. Yater et al (1936) explained this possibility by suggesting the presence of one pacemaker in one of the bundle-branches sending impulses directly to the Purkinje network of the other side through the interventricular septum. One last possibility is the presence of a focus situated in the septum, below the bilateral bundle-branch block, in a position equidistant from both bundle-branches.…”

The introduction of the artificial electrical pacemaker for the treatment of patients with complete A-V block has been accompanied by renewed interest in the pathogenesis of this disorder. It has been considered that most cases of complete block are due to organic or functional lesions either in the A-V node or in the common A-V bundle. Barker conduction through both bundle-branches was unequally impaired. In both of these situations, one would observe a complete right or left bundlebranch block with prolongation of the P-R interval.Complete block would be the manifestation of failure of conduction through the more depressed branch, while prolongation of the P-R interval would be the manifestation of depressed conduction through the less impaired branch. They stressed that true bilateral bundle-branch block must show a prolonged A-V conduction time. Mahaim (1931), and more recently Lenegre and Moreau (1962), and Lenegre (1964), have conducted pathological studies in the hearts of patients who had complete A-V block. They confirmed the electrocardiographic impression that in the great majority of patients this type of block was due to an anatomical bilateral bundle-branch block.To elucidate further the relation between bilateral bundle-branch block and A-V block, we have analysed the records of all patients with complete A-V block admitted to the University Hospital, Saskatoon, in the five-year period between 1960 and 1965. Patients with surgical A-V block and those in whom the history and clinical diagnosis suggested digitalis toxicity were excluded. The results of our study form the basis of this communication.SUBJECTS AND RESULTS Between 1960 and 1965, 57 patients with an electrocardiographic diagnosis of complete A-V block were studied at the University Hospital. In many instances previous electrocardiograms were available. The age of the patient, the clinical history, and electrical axis in the frontal plane were carefully recorded.The 57 patients were divided into two main groups, according to the contour of the ventricular complexes during the periods of complete A-V
