WebbThe Purkinje fibers transmit the signals more rapidly to stimulate contraction of the ventricles. [2] The conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG. WebbPurkinje fibers contain a special type of cardiac muscles that make them the most efficient and quickest conductors of impulses in the cardiac system. The histology of these muscles reveals that they have thinner muscle fibers with fewer muscle strands than normal cardiac cells, which makes them appear lighter than other cells in a stained slide. dyscognitive features
