The conduction system consists of specialized heart muscle fibers that transmit electrical impulses to regulate atrial and ventricular contraction. These modified fibers are separated from the ordinary myocardial fibers by delicate envelopes of connective tissue.

The Conducting System
The Conducting System. Introduction The heart's conducting system consists of the . sinoatrial node (SA node), atrioventicular node (AV node), the bundle of His, the bundle branches and the Purkinje fibers. The electrical impulse that causes rhythmic contraction of heart muscles arises in the . SA node. which is the intrinsic pacemaker of the ...

Heart Physiology: Intrinsic Conduction System • Initiate action potentials • Have unstable resting potentials called pacemaker potentials • Use calcium influx (rather than sodium) for rising phase of the action potential. Na + ions initiate myocyte depolarization & are responsible for conduction through the myocardium ...
