Investigations were performed in human embryos of stage 15th and 16th (33 to 40 postovulatory days). The atrioventricular part of the conducting system develops in the place of junction of the rings which separate particular parts of the heart tube. In embryos of stage 15th the sinuatrial node, atrioventricular node, and atrioventricular bundle are already visible.
