本文对15只家兔心脏传导系统进行了解剖学研究。家兔的窦房结是一个简单而独特的结构，位于界嵴与腔静脉窦的交界处，几乎位于两个腔的中间;它含有异常大比例的P细胞，但没有组织在一个大的中央动脉周围。房室结和希氏束相对较小，并被家兔通常存在的大冠状窦向前移位，因为其存在左上级腔静脉。房室结由输入系统和旁路束组成，类似于人和狗的房室结。房室结和希氏束是否含有许多明显的大神经干。窦房结的血液供应来自右冠状动脉和左冠状动脉的末端小分支，而房室结和希氏束的血液供应仅来自间隔动脉的类似末端分支。这些解剖特征的可能的功能意义进行了讨论。
Anatomy of the cardiac conduction system was studied in 15 rabbits with serial histologic sectioning of 4. The rabbit's sinus node is a simple and distinct structure located at the junction of the crista terminalis with the sinus intercavarum nearly midway between the two cavae; it contains an unusually large percentage of P cells but is not organized about a large central artery. The AV node and His bundle are relatively small and are displaced anteriorly by the large coronary sinus normally present in the rabbit because of its persisting left superior vena cava. The AV node is organized with input system and bypass tracts similar to those of man and the dog. Doth the AV node and His bundle contain many conspicuously large nerve trunks. The blood supply of the sinus node is from terminal small branches of both the right and left coronary arteries and that to the AV node and His bundle is from similar terminal branches of the septal artery only. The possible functional significance of some of these anatomic features is discussed.
