Place the following components of the cardiac conduction pathway in the correct anatomic order
1 . Atrioventricular node
2 . Bundle branches
3 . Bundle of His
4 . Internodal pathways
5 . Purkinje fibers
6 . Sinoatrial node
a. 6, 1, 4, 3, 2, 5 c. 6, 1, 4, 2, 3, 5
b. 6, 1, 3, 2, 4, 5 d. 4, 3, 2, 5, 6, 1
A
The three main areas of impulse propagation and conduction are (1) the sinoatrial node, (2) the atrioventricular node, and (3) the conduction fibers within the ventricle, specifically the bundle of His, the bundle branches, and the Purkinje fibers. Interruption or malfunction of any part of the conduction pathway can result in dysrhythmias specific to that structure.
