• Blood pressure

• The lub and dub heart beat sounds

• The hematocrit value of the red blood cells

• The electrical impulses of the heart

What condition does this person have?

• normal EKG

• systole

What condition does this person have?

What does the QRS complex represent?

• Atrial contraction

• Ventricular depolarization

• Ventricular relaxation

• Blood flow through the heart

Which wave indicates ventricular repolarization (relaxation)?

• P wave

• QRS complex

• T wave

• U wave

Which wave on an EKG represents the electrical activity initiated by the SA node?

• P wave

• Q wave

• T wave

• U wave

Fat and cholesterol can build in the walls of blood vessels and tear causing blood platelets to build and block blood from reaching the heart. This then can cause heart muscles to die. This is considered a

• Heart attack

• Stroke

• Atrioventricular node (AV)

• Purkinje fibers

If an EKG is lacking a P wave, it typically indicates that the

• The SA node is not functioning properly

• Blood pressure is too high

• heart muscle cells are dying

• heart is tachycardic

Which of the following can lead to tachycardia? Select 2.

• High blood pressure

• Low blood pressure

• Sleep apnea

• Stress

• myocarditis
