The authors present a simplified technique to visualize the left bundle of His in the human heart, facilitating anatomical and electrophysiological studies of the conduction system.
Visualization of the atrioventricular node and bundles of His in the human heart has been very difficult in the past, so much so that the very existence of specialized conducting tissue in man has been questioned. The authors present a simplified technic permitting visualization of the left bundle of His that facilitates studies in this area.
Uhley et al. (Tue,) studied this question.
