Quiz on the Electrical Conduction System of the Heart | Anatomy & Pathophysiology

This quiz will test your knowledge on the electrical system of the heart. In nursing school, especially in your pathophysiology or anatomy class, you will have to know how the Sinoatrial node (SA node), Atrioventricle node (AV node), Bundle of His, right and left bundle branches, and Purkinje fibers work to make the heart contract.

After contraction of the heart due to the electrical system, which contributes to the blood flow of the heart throughout the body, it must supply your tissues, organs, and brain with the nutrients it needs to function.

Video Tutorial on Electrical System of the Heart

Before you take the quiz, watch this teaching tutorial by registered nurse S.L. Page give an easy explanation on how the electrical conduction system of the heart works.

Quiz on the Electrical Conduction System of the Heart Anatomy & Pathophysiology

This quiz will test your knowledge on the electrical system of the heart. You will be tested on your ability to differentiate between the SA & AV nodes, purknije fibers, bundle branches, and how they conduct electricity to the heart for repolarization and depolarization.

What area of the heart's electrical conduction is known as the "pacemaker" of the heart?*
- Purknije Fibers
- AV node
- Bundle of His
- SA node
What area of the heart is responsible for the delay of conduction between the artrium and ventricles?*
- Bundle of His
- Right bundle branch
- Bachmann's Bundle
- AV node
True or False: Bachmann's bundle is located in the left artrium.*
- True
- False
True or False: Depolarization of the heart muscle is when the muscle contracts and repolarization is when the heart muscle rests.*
- True
- False
The SA node fires at a rate of?*
- 60-80 bpm
- 40-60 bpm
- 80-90 bpm
- 60-100 bpm
On an EKG the P-wave represents what area of the heart?*
- Left bundle branch
- SA node
- Bachmann's Bundle
- AV node
What part of the heart's electrical system is known as the "gatekeeper"?*
- Gap Junction
- SA node
- Tetany
- AV node
What area of the heart forms the PR segment on the EKG?*
- AV node and Right and Left Bundles
- Apex of heart
- Bundle of His
- Purkinje fibers
What area of the heart forms the QRS part on an EKG?*
- Purkinje fibers
- SA node
- AV node
- Left and right bundles
True or False: The SA node is located in the Left atrium.*
- True
- False
What is the correct sequence of electrical conduction of the heart?*
- AV node, internodal pathways, SA node, Bundle of His, Right and Left Bundle Branch, Purkinje fibers
- None of the options are correct
- SA node, internodal pathways, AV node, Bundle of His, Right and Left Bundle Branch, Purkinje fibers
- SA node, internodal pathways, AV node, Purkinje Fibers, Right and Left Bundle Branch, Bundle of His
