EKG

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

• QRS
• P-Q wave
• P wave only 
• T wave

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

• T-wave  
• S-T waves
• R wave 
• QRS

If there is a flat P wave which structures int he 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 AV node is located at...

• A
• B
• C
• D

The Purkinje fibers are located at...

• F
• G
• H
• I

The components that indicate the QRS complex is...

• a,b,c
• b,c,d
• c,d,e
• b,d,e

The QRS-wave correlates with which event?

• atrium contraction /signals moving from SA node to AV node
• ventricle contraction
• ventricle repolarization
• both atrial and ventricle contraction
