The Cardiac Conduction System
https://www.ccnursing.theclinics.com/article/S0899-5885(16)30027-2/pdf
The cardiac conduction system is composed of the SA node, the AV node, the bundle of His, bundle braches, and the Purkinje network. As mentioned previously, the heartbeat originates from the SA node in the upper right atrium and has the primary responsibility for the heart’s electrical activity.

A pacemaker is required to restore a normal heart rate and correct the slowing down of the natural electrical conduction tissue. This is most commonly due to the conduction system ‘wearing out with age’, but can also occur as a congenital (in-born) problem or as the result of a heart attack, infection, or particular medications.

The cardiac conduction system coordinates the heart’s elec-trical activation. Electrical impulse generation begins in the sinoatrial (SA) node and sequentially propagates activation of the atria, atrioventricular (AV) node, His and Purkinje systems, and ventricles.

In this article, the focus is on abnormalities in rhythm and electrical con-duction that can be identified on an ECG. Cardiac arrhythmias and conduction defects are common. They can be an acute problem presenting for the first time, or part of a chronic disease course compli-cated by acute decompensation at periods of illness.

The CRT or conduction system pacemaker (also known as a bi-ventricular pacemaker) is not like the traditional pacemakers used for slow heartbeats. This pacemaker is implanted with the aim of totally taking over the job of the heart’s electrical conduction system and getting the lower chambers of the heart (ventricles) to pump together.

The normal cardiac-conduction-system is responsible for the contraction of the heart muscle. Damage or irregular function of the cardiac conduction system can lead to serious and, in some cases, fatal clinical events. Every cardiac myocyte has the potential of contracting when stimulated with an adequate impulse. Electrical impulses are …

The conduction system of the heart is shown in Fig. 1.1. The sinoatrial node (S-A) has the highest rate of spontaneous depolarization and acts as the primary pacemaker. At normal condition, the S-A node generates impulses that stimulate the atria to contract. This node is located in the superior wall of the right atrium, close to the opening of the superior vena …

In a normal heart the pacemaker cells are the only cells initiating depolarization. Pacemaker cells can be found throughout the hearts electrical conduction system (See Figure 4). The Sinoatrial Node (SA Node) is a cluster of pacemaker cells located above the right atrium and is the main pacemaker of the heart.

An arrhythmia is an abnormal heart rhythm. Your heart has an electrical conduction system which makes your heart pump blood around your body. Arrhythmias are caused by an abnormality in that electrical conduction system, and can make your heart beat too slowly, too quickly, or in an irregular way. Some arrhythmias are more serious than others.

Your heart has its own electrical conduction system which sends signals throughout the upper chambers (atria) and lower chambers (ventricles), making it beat in a regular, coordinated rhythm. The sino-atrial node (SA node) fires an electrical impulse and is responsible for setting the rate and rhythm of a normal heartbeat.
