Further histologic examination reveals that these fibers are split in ventricles walls. The electrical origin of atrial Purkinje fibers arrives from the sinoatrial node See more Heart rate is governed by many influences from the autonomic nervous system. The Purkinje fibers do not have any known role in setting heart rate unless the SA node is compromised (when they can act as pacemaker cells). They are influenced by electrical discharge from … See more Purkinje fibers are named after the Czech scientist Jan Evangelista Purkyně, who discovered them in 1839.
