Question

An ekg tech notes that the QRS complex is too tall to fit on the ekg paper. Which of the following actions should the tech take?

1. change the gain control to 20 mm/mv
2. change the paper speed to 10 mm/sec
3. change the gain control to 5 mm/mv
4. change the paper speed to 50 mm/sec

Answer 1

To fit the QRS complex on the EKG paper, the EKG tech should change the gain control to 5 mm/mV.

Step-by-step explanation:

To fit the QRS complex on the EKG paper, the EKG tech should change the gain control to 5 mm/mV. This will reduce the height of the QRS complex on the paper. Changing the gain control to 20 mm/mV would make the QRS complex even taller, so that is not the correct action to take. Similarly, changing the paper speed would not affect the height of the QRS complex.
