Cardiac Conduction and EKG's

An electrocardiogram measures what?

• The amount of pressure exerted on blood vessels.
• The electrical activity of the heart.
• How many times the heart contracts over time.
• The body's temperature caused by friction of blood in vessel.

What do the letters EKG stand for?

• Electrocardiograph
• Electromagneticgraph
• Electrocardiogram 
• Electrolytes

What letters are used to label the parts of an EKG?

• PQRST 
• ABCDE
• ACDC
• DNAI

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

• Sino-atrial node 
• right atrium
• atria-ventricular node 
• left ventricle

The t-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?

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

The nurse is reviewing a patient’s electrocardiogram. Which wave should the nurse recognize as being the first positive wave in a normal cardiac cycle?

• P wave

• Q wave

• R wave

• S wave
