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 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

Located in the proximal intraventricular septum. It merges from the AV node to begin the conduction of the impulse from the AV node to the ventricles.

• Bundle of His

• ST segment

• T wave

• Electrode

A small rounded wave on an EKG that indicates atrial contraction.

• T wave

• AV node

• P wave

• SA node

Specialized heart conducting tissue that receives impulses from the SA node and propagates them to the ventricles.

• AV node

• SA node

• AS node

• VA node
