|
SA Node
|
|
|
AV Node
|
|
|
AV Bundle
|
|
|
Purkinje Fibers
|
Explanation:
Detailed explanation-1: -They send electrical signals very quickly to your right and left heart ventricles. Your Purkinje fibers are in the subendocardial surface of your ventricle walls. The subendocardial surface is part of the endocardium, the inner layer of tissue that lines your heart’s chambers.
Detailed explanation-2: -The ventricular conduction system (VCS) entails components of the cardiac conduction system distal to the atrioventricular node and includes the Bundle of His, right and left bundle branches as well as the Purkinje fiber network (Figure 1).
