The Conducting System
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.

The electrical impulses generated by the heart’s conduction system begin in the . sinoatrial node (SA node), which is located in the upper wall of right atrium (Figure 1) near the entrance of the superior vena cava. Since the heart’s electrical activity begins with the SA node, it is known as the pacemaker of the heart.

As the heart depolarizes the muscles contract. It is the movement of this electrical charge that creates the deflections known as EKGs. I know this is all review but it makes EKGs so much easier to understand with these few basic facts. The conduction system through the heart. SA ( AV ( Bundle of His ( Left and Right Bundle Branches

The normal electrical flow through the heart originates in the SA node>AV node>Bundle of His> left and right bundle branches> Purkinje fibers where the mechanical cells are stimulated. The primary pacemaker therefore is the SA node and has an inherent rate of 60-100 beats/minute.

Understand how conduction of electrical signals through the heart can be detected as an electrocardiogram (ECG or EKG). Understand the relationships between ECGs, blood pressures, blood flows, and the opening and closing of cardiac valves.
