Gross anatomy and histology of the cardiac conducting system of Gallus domesticus has been studied. Detailed histology of the atrium revealed for the first time, in the avian heart, the presence of three atrial bundles which communicate between the sinuatrial node and the atrioventricular node. Purkinje fibres in the subendocardium of the right atrium are observed. An atrioventricular segment comprising of the posterior end of the interatrial septum and the atrioventricular nodal region has been reported in which the three atrial bundles converge. The role of the atrial bundles in the cardiac contraction has been discussed.
对家鸡心脏传导系统的大体解剖和组织学进行了研究。心房的详细组织学首次揭示了在鸟类心脏中，存在三个在窦房结和房室结之间连通的心房束。观察到右心房心内膜下层的浦肯野纤维。据报道，一个由房间隔后端和房室结区域组成的房室段，三个心房束在此汇聚。讨论了心房束在心脏收缩中的作用。
