His-purkinje network function
Webb19 jan. 2015 · The Purkinje network functions to distribute a stimulus throughout the entire ventricles, leading to a much faster total activation of the ventricles than could be … Webb18 juli 2024 · Purkinje fibers rapidly relay cardiac impulses to the myocardium (middle heart layer) of the ventricles causing both ventricles to contract. Myocardium is thickest in heart ventricles allowing ventricles to generate enough power to pump blood to the rest of the body. The right ventricle forces blood along the pulmonary circuit to the lungs.
