Front

What is a wandering baseline in EKG readings?

Back

A wandering baseline is an artifact that appears as drifting away from the center of the EKG tracing, often caused by patient movement or poor electrode contact.

Front

What should an EKG technician say to an 8-year-old patient when preparing for a 12-lead EKG?

Back

The technician should say, 'I’m going to apply some stickers to your belly, arms, and legs for the test.' This is a simple and clear explanation appropriate for a child.

Front

What does it indicate if a patient understands the instructions for wearing a cardiac event monitor?

Back

The patient indicates understanding by saying, 'I will continue to do my daily walk to the grocery store,' showing they know they can maintain normal activities.

Front

What do elevated ST segments during an exercise stress test indicate?

Back

Elevated ST segments are signs of acute myocardial injury, which may suggest that the heart is not receiving enough oxygen.

Front

What is AC interference in EKG readings?

Back

AC interference is an artifact caused by electrical signals from external sources, which can distort the EKG tracing.

Front

What is the role of electrodes in an EKG?

Back

Electrodes are placed on the skin to detect the electrical activity of the heart and transmit this information to the EKG machine.

Front

What should a patient avoid while wearing a cardiac event monitor?

Back

Patients should avoid activities that may interfere with the monitor's function, such as using electric blankets or taking showers.

Front

What is the significance of ST segment changes during an exercise stress test?

Back

ST segment changes can indicate ischemia or other cardiac issues, helping to evaluate the patient's heart health.
