Quiz EKG And Telemetry
Telemetry monitoring and EKGs both monitor a patient's heart activity. While the two systems are similar in many ways, they vary in some key areas. As such, it's not uncommon for people to wonder about the difference between what telemetry technicians and EKG technicians do. Take the test and see if you can note the difference.
