Purkinjeszálak
Purkinje fibers are specialized cardiac muscle cells that form part of the electrical conduction system of the heart. They are named after the Czech physician Jan Evangelista Purkyně, who first described them in 1839. These fibers are responsible for rapidly transmitting the electrical impulse from the bundle of His to the ventricular myocardium, ensuring a coordinated contraction of the ventricles.
Originating from the bundle branches, Purkinje fibers are characterized by their large diameter, pale cytoplasm, and
The electrical impulse generated by the sinoatrial (SA) node travels through the atria, reaches the atrioventricular
