A system originating from the natural pacemaker (Sinus) and ending in cells in the ventricles.
This system is capable of rapid transfer of electrical stimuli.
Its composition and structure assure that electric stimuli are transferred in a fully synchronized manner, i.e. each electrical pulse emerging from the Sinus reaches the cells in the ventricles at exactly the same time, which enables effective and powerful contraction.
With age, the conduction systems may be subject to different degenerative processes that in some cases necessitate the implantation of an artificial pacemaker.
