• PR segment

• QRS complex

If the P wave on an EKG looks abnormal, which structures in the heart are likely damaged?

• SA/AV node

• Aortic valve

• Bundle of His

• Purkinje fibers

The p-wave correlates with which event?

• atrial depolarization

• ventricle depolarization

• ventricle repolarization

• atrial repolarization

What does repolarization result in?

• relaxation

• contraction

• attraction

• repulsion

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 is going on in the heart during the R-wave or QRS complex

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle, the main pumpung action
• Delay caused by the SA node
• Repolarization of the ventricle 

What is going on in the heart during the T-wave

• SA node triggers depolarization in atria
• AV node triggers depolarization in ventricle, the main pumpung action
• Delay caused by the SA node
• Repolarization of the ventricle 

Which of the following describes the network that distributes electrical impulses throughout the heart?

• cardiac conduction system

• electrocardiogram

• HECO

• action potential network

Intrinsic electrical impulses start at which of the following locations?

• AV Node

• Bundle of His

• Purkinje fibers

• SA Node
