NCLEX Review:Electrical Conduction System of the Heart
In this NCLEX review video, we are going to look at how the rhythm of the heart is controlled by electrical impulses. We will start with a refresher of the four heart chambers before we begin our discussion of the cardiac conduction system. Once we define what this system is, we will explore topics that you will need to know for your upcoming NCLEX exam, including: the SA node, the AV node, the Bundle of His, the Purkinje fibers, depolarization and repolarization. We will finish by reviewing the heart’s conduction system in five easy steps.
