EKG Part 1

What does EKG stand for?

• Electrocardiology

• Electrocardiograph

• Electrocardiography

• Electrocardiogram

What is the main purpose of an EKG?

• To assess lung function

• To measure blood pressure

• To detect and diagnose heart problems

• To monitor brain activity

Which part of the heart is responsible for pumping oxygenated blood to the body?

• Left ventricle

• Left atrium

• Aorta

• Right ventricle

What is the normal heart rate range for adults?

• 60-100 beats per minute

• 20-40 beats per minute

• 120-150 beats per minute

• 200-250 beats per minute

What is the correct sequence of electrical conduction in the heart?

• AV node → SA node → Bundle of His → Purkinje fibers

• SA node → Bundle of His → AV node → Purkinje fibers

• SA node → AV node → Bundle of His → Purkinje fibers

• SA node → AV node → Bundle of His → Atria

What does the QRS complex represent in an EKG?

• Depolarization of the atria

• Repolarization of the atria

• Depolarization of the ventricles

• Contraction of the atria

What is included in an accurate, up-to-date medical record?

• Only demographic information

• Patient history but no insurance information

• Only laboratory reports

• All information relevant to patient medical care and insurance
