A simple dissection method for the conduction system of the human heart

Nariaki Yanagawa, Yuji Nakajima

Abstract

A simple dissection guide for the conduction system of the human heart is shown. The atrioventricular (AV) node, AV bundle, and right bundle branch were identified in a formaldehyde-fixed human heart. The sinu-atrial (SA) node could not be found, but the region in which SA node was contained was identified using the SA nodal artery. Gross anatomical observation of the conduction system is useful for understanding the structure and function of the heart.
