A4 QRS complexes correspond to a heart rate of 60 bpm
B10 QRS complexes correspond to a heart rate of 100 bpm
C8 QRS complexes correspond to a heart rate of 100 bpm
D6 QRS complexes correspond to a heart rate of 80 bpm
✓ Correct answer: B. 10 QRS complexes correspond to a heart rate of 100 bpmAnswer: 10 QRS complexes correspond to a heart rate of 100 bpm. To use the six-second strip method, count the number of QRS complexes within a 6-second interval and multiply that number by 10 to calculate the heart rate in beats per minute (bpm). For example, if there are 10 QRS complexes in six seconds: $$10 \times 10 = 100$$ bpm.
