Question

When performing a stress test, an EKG technician should recognize that the test can be stopped when the patient reaches what percentage of their target heart rate?

1) 25% to 40%
2) 45% to 60%
3) 65% to 80%
4) 85% to 100%

Answer 1

During a stress test, the EKG technician should stop the test when the patient reaches 85% to 100% of their target heart rate or if there are significant symptoms or concerning EKG changes.

Step-by-step explanation:

When performing a stress test, an EKG technician should recognize that the test can be stopped when the patient reaches 85% to 100% of their target heart rate. The target heart rate is often calculated using the formula 220 minus the patient's age, and during a stress test, the goal is typically to reach 85% of this maximum heart rate. However, it may be terminated earlier if the patient experiences significant symptoms or if the EKG shows worrying changes.
