OBSERVATIONS ON THE AURICULO‐VENTRICULAR JUNCTION OF THE MAMMALIAN HEART

Abstract

The muscular connection between auricle and ventricle in the heart of man is not single and confined to the A.V. bundle, but it is multiple. One point at which a muscular connection between auricle and ventricle exists is situated at the right margin of the heart. The coordinated action of the chambers of the heart is to some extent dependent upon the integrity of muscular connections other than that which exists in the A.V. bundle. It is proposed, for purposes of identification, to refer to the connection described as the “right lateral” connection. © 1913 The Physiological Society
