Webbprecursors of the Purkinje network (de Jong et al. 1992, Sedmera et al. 2004), it is clear that not all the trabeculae will turn into Purkinje fibers – in fact, the majority will form trabeculae carneae, or “meaty” trabeculations composed largely of working myocardium, that we find on the inside of the ventricles. As noted above, our 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. shannon nelson obituary

"WebbThese bundles and fascicles give rise to thin filaments known as Purkinje fibers. These fibers distribute the impulse to the ventricular muscle. The ventricular conduction system comprises the bundle branches and the Purkinje networks. It takes about 0.03–0.04 seconds for the impulse to travel from the bundle of His to the ventricular muscle . " - The purkinje fibers are indicated by
