Q
Evaluate the RATE
You can use several methods to evaluate the rate
Name three?
A
You can use several methods to evaluate the rate:
- Count the number of QRS complexes in a 6 second strip and multiply by 10
- Count the number of QRS complexes in a 3-second strip and multiply by 20
- Triplicate Method/300 Rule
