Description:Excerpt from American Society for Testing Materials, Vol. 12: Affiliated With the International Association for Testing Materials Uink is aj: parenlly iKrnial. Sections of the auriculoventricular bundle show an old sclerotic lesion of the main stem shortly after the oriiin of the bundle, causiui- a complete trans-erse lesion. I1ie diainosis of aurictilar hbrillation and heartblock had been made on the ground that the ventricular rhythm was regular in the presence of auricular librillation. The presence of auricular hbrillation was established l)y means of electrocardiograms. Sections of the sino-auricular node of the second case showed a very slight degree of fibrosis. A few small haemorrhages (probably ante-morteiu) and one area of round cell infiltration were seen. Tlie auriculo-entricular l)un(lle in this case was not interrui)ted. The absence of the A-wae from the jugular pulse, together with complete entrictllar irregularity, made it likely even without electric curxes, that the auricles in this case, too, were fibrillating. It was sui)pose(l that the A- Ijundle was capable of conducting imptilses. There were i)erio(ls wlien the l)radycardia ga e)lace to a relatixe tachycardia, but the rbxtlim was always irregular. The two cases are shown together to bring out the fact that accurate clinical diagnosis in these com)licated conditions can be made with certainty. The fact that there was an extensive lesion of the node in one case and a relativel slight lesion in the other renders it unlikeh tliat these lesions are responsible for auricular fi)rillalijn. Ihe transxerse lesion of tlie node in one case and a relati ely slight lesion in tlie other renders it unlikely that these lesions are resi)onsible for aiUMcular fibrillation. The transverse lesion oi ihtA A bundle in the lirst case determined the regular rlnlhm;while the intact )undle in the second made a complete ventricular irregularity )ossil)le. Jlie elinlogieal I actor in the lirst case was sphilis. The patient was also a hea ysmoker and diinker. The second case was one of arierio sclerosis. The patient liad een a heavy worker and sniokc-r.
