What is the function of autorhythmic cells in the heart? What are these cells called and what is their role? Autorhythmic cells are cardiac muscle cells that produce action potentials in the heart when stimulated by a pacemaker of the heart. The AV node transmits action potentials from the atria to the ventricles. Autorhythmic cells are smooth muscle cells that produce spontaneous action potentials. Cells within the AV and SA nodes are autorhythmic. The AV node acts as the pacemaker of the heart. The SA node transmits action potentials from the atria to the ventricles. Autorhythmic cells are skeletal muscle cells that produce spontaneous action potentials. Cells within the AV and SA nodes are autorhythmic. The AV node acts as the pacemaker of the heart. The SA node transmits action potentials from the atria to the ventricles.
