5. Bundle branches carry the impulse toward the apex of the heart. 6. Purkinje fibers carry the impulse to the heart apex & ventricular walls. Extrinsic Innervation of the Heart • Heart is stimulated by the sympathetic cardio-acceleratory center • Heart is inhibited by the parasympathetic cardio-inhibitory center. Electrocardiography

B. Heart failure is a progressive weakening of the heart as it fails to keep pace with the demands of pumping blood and thus cannot meet the body’s need for oxygenated blood. (pp. 545–546) C. Disorders of the conduction system include atrial and ventricular fibrillation. (p. 548) IX. The Heart Throughout Life (pp. 548–551, Figs. 18.17 ...
Electrical conduction system of the heart - Wikipedia
The cardiovascular system is the first system to function in the embryo. It is functioning by the end of the third week of development. You will learn in the heart lecture that the heart has a nervous system all its own known as the conduction system.

The mechanical pumping action of the heart can occur only in response to an electrical stimulus. The electrical conduction system consists of the sinoatrial (SA) node, the atrioventricular (AV) node, the bundle of His, the right and left bundle branches, and the Purkinje fibers. Cardiac muscle cells have a special characteristic called automaticity.
