Interpreting EKG Interpretation 20 question Quiz

What is the primary goal of learning to interpret EKGs?

• To understand the patient's blood pressure

• To interpret the patient's heart rhythm

• To measure the patient's oxygen levels

• To assess the patient's lung function

What do the dark and lighter lines on EKG graph paper represent?

• Heart rate and blood pressure

• Large boxes and small boxes

• Electrical activity and muscle contraction

• Time and amplitude

What does the vertical axis on the EKG graph paper represent?

• Time
