The structure of the atrioventricular conducting system in the avian heart
The Anatomical Record, 1986AbstractThe atrioventricular conduction system in three avian species has been studied by light and electron microscopy. A morphologically definable atrioventricular node was not found in any of these. The atrioventricular bundle is a well‐defined structure, the proximal portion of which is in direct continuity with the atrioventricular ring, located ...

The heart of the rat with special reference to the conducting system
American Heart Journal, 1954Abstract 1. 1. The sinuatrial node is absent in the rat. It develops in relation with and consequent to the reduction of the sinus venosus. 2. 2. The sinuatrial valves are rectangular padlike structures. They enter deep into the cavity of the right atrium.

Mayo Clinic Proceedings, 1984 Vascularization of the conducting system in the human heart
Cells Tissues Organs, 1978On 200 randomized specimens of the human heart, of either sex, from 20 to 80 years of age, we investigated the vascularization of the conducting system of the heart in relation to the type of coronary ramification, by the dissection, injection-corrosive, radiographic and coronarographic method.

The Road to Unearthing the Conducting System of the Heart
2020The essence of the heartbeat remained a mystery for centuries. William Harvey, in his description of the circulation of blood, did not explain the origin of the heartbeat. He stated that “the pulse has its origin in the blood…the cardiac auricle from which the pulsation starts, is excited by the blood.” It was held for several centuries that the ...
