What arrhythmia would you expect to find on a healthy athlete?
sinus bradycardia
When finished performing an EKG what should the CET do?
Check for artifacts before printing/documenting

lead I
A wandering baseline is showing up on the tracing. What should the CET do?
This lead is also the 5th lead in a 5 lead EKG

An EKG tech is performing a stress test on a patient who becomes unresponsive and has no pulse. The tech attaches the AED to the patient and administers a shock. What is the next step?
Continue performing CPR
What is the cause for discontinuing a stress test?
ST elevation or depression
What should you do if you see this rhythm during a stress test?
Stop the test
When performing a stress test you must record this many blood pressure readings before applying the electrodes
