The ventricular conduction system - ultrastructure and function.

The ultrastructure and function of the ventricular conducting system in animals are briefly reviewed. As the ventricular conducting cells are resistant to anoxia, an adequate ultrastructural preservation has been obtained in human autopsy material. In a case of cardiomyopathy, abnormalities in the conducting cells are related to current theories of abberant cardiac rhythm. We propose that further knowledge of the human conduction system can be obtained by extended studies of this kind.
