EKG QUESTIONS

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

• SA/AV node

• Bicuspid valve

• Bundle of His

• Purkinje fibers

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 QRS-wave correlates with which event?
