EKG

P Wave

• SA Nodes contracts

  Both atria contracts

• Impulses reach the av node 0.10 delay allows

• Repolarization or recovery of the ventricles

• Impulses hit av bundle branch off into two bundles down front of heart into purkinje fibers

QRS

• Repolarization or recovery of the ventricles

• Impulses hit av bundle branch off into two bundles down front of heart into purkinje fibers

• SA Nodes contracts

  Both atria contracts

• Impulses reach the av node 0.10 delay allows atria

What do the letters EKG stand for?

• Electrocardiograph
• Electromagneticgraph
• Electrocardiogram 
• Electrolytes

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.

An EKG is actually

• A ratio
• An equation
• A time frame
• A graph 

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
