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 letters are used to label the parts of an ECG?

• PQRST 
• ABCDE
• ACDC
• DNAI

Which of the following is not a direct indicator of a person's cardiac health?

• Heart Rate
• Blood Pressure
• ECG
• Temperature 

The p-wave correlates with which event?

• atrial systole/signals moving from SA node to AV node
• ventricle systole
• ventricle repolarization
• both atrial and ventricle diastole

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

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

Identify in the image where the t-wave is (represented by which letter)?

• a - atrium contraction /signals moving from SA node to AV node
