Reaffirmation of the Auriculoventricular Conduction System in Man
The Introduction of a Unique Technic for Its Serial Motion Picture Reconstruction
Gross and microscopic studies of the auriculoventricular conduction system were performed in 60 human hearts. A unique technic is introduced which will produce a photographic record of undistorted serial sections through a block containing the auriculoventricular node, auriculoventricular bundle and branches. By projecting the completed film as a motion picture, the course and changing relationships of component structures can be followed from level to level in uninterrupted sequence. The neurogenic versus the myogenic concept of cardiac conduction is reviewed at length.
