Purkinje fibers are specialized conductive myocardial cells with few myofibrils that promotes the rapid conduction of the impulse through the ventricles. They are larger than the normal myocardial fibers. The waves of depolarization ultimately spread to adjacent myocardial cells through the intercalated discs.

The Purkinje fibers are functional conducting fibers, that are comprised of electrically excitable cells and are larger than the normal myocardial fibers. The Purkinje fibers are of the huge number of mitochondria and which fibers conduct cardiac action potentials more speedily and efficiently than any other cells in the heart. Purkinje fibers from dogs and sheep are the most frequently used; however, fibers have also been obtained from other animals such as calves, pigs, goats, and rabbits. The number of usable fibers varies with each heart, and in the dog ranges from three to eight.

Fast-twitch extremity muscle fibers are preferentially affected in Duchenne's and Becker's muscular dystrophy. Since saccades are thought to 

Disorders involving the Purkinje cells usually negatively affect the patient's movement. The Purkinje cells may be affected by both genetic and acquired disorders. Purkinje fibers were named after a Czechoslovakian anatomist named Jan Evangelista Purkyne. At the base of the heart, the atrioventricular bundles start to divide further into Purkinje fibers. When the impulses reach these fibers they trigger the muscle fibers in the ventricles to contract. The right ventricle sends blood to the lungs via the pulmonary artery. The left ventricle pumps blood to the aorta.
