Reduction of Risk PotentialQuestion 756 of 2368
A 6-second rhythm strip shows 9 R waves. What is the ventricular rate?
- 54 beats per minute
- 60 beats per minute
- 90 beats per minute
- 900 beats per minute
Show answer
Correct answer: 90 beats per minute
The ventricular rate is found by counting the R waves in a 6-second strip and multiplying by 10, so 9 times 10 is 90.
