Demonstration of Peripheral Conduction System in Human Hearts
The peripheral conduction system was demonstrated grossly by iodine staining in a normal newborn heart and in one with a muscular ventricular septal defect. Staining of the conduction system was unsuccessful in a third heart when attempted over 2 hours after death. The left ventricular conduction system was easily visualized; however, the arborizations of conduction tissue over the right ventricular free wall endocardium were demonstrated poorly.
