EKG Basics

Which letter(s) indicates the health of the atria?

• QRS

• P-Q wave

• P wave only 

• T wave

If there is a flat P wave which structures in the heart are damaged?

• SA/AV node

• Bicuspid valve

• Bundle of His

• Purkinje fibers

If the p-wave is high/irregular. What is happening to the atria chamber? 

• Blood is traveling too fast

• Blood is remaining in the chamber 

• SA node is damaged

• Heart is not getting enough Oxygen

The place where the electrical current starts and is considered the heart's pacemaker:

• Sino-atrial node 

• right atrium

• atria-ventricular node 

• left ventricle

The p-wave correlates with which event?

• atrium contraction /signals moving from SA node to AV node

• ventricle contraction

• ventricle repolarization

• both atrial and ventricle contraction

The components that indicate the QRS complex is...

• a,b,c

• b,c,d

• c,d,e

• b,d,e

What is the T wave located?

• A

• B

• C

• D

• E

What does depolarization result in?

• relaxation

• contraction

• repulsion

• attraction

Where is the AV node located?

• A

• B

The normal heart rhythm is called?

• Sinus brady

• ventricle fibrillation

• Normal sinus rhythm

• Junctional Rhytms
