Hemiblocks are partial and occur within one or more fascicles of the atrioventricular … WebThe bundle branches lead to the Purkinje fibers, which carry out the contraction of the ventricular muscles, approx. 0.15 seconds after the atria have contracted.It takes less than 0.05 seconds for the impulse to travel from the bundle of His to the Purkinje fibers. This contraction generates the force necessary to force the blood out of the ventricles.
