The nurse is reading an ECG rhythm strip and notes that there are nine QRS complexes in a 6-second strip. The heart rate is:
1. 36.
2. 54.
3. 81.
4. 90.

A heart rate can be determined by multiplying the QRS complexes in a 6-second strip by 10. The heart rate is 90. This method of calculating the heart rate is the most common method used because it is quick and can be used when the heart rate is irregular.
