Heart rate (in beats per minute) is calculated by dividing 60 by the _____ (in seconds).Multiple choice question.R-R intervalPQ segmentP wave frequencyQRS complex amplitude

How do you calculate heart rate in beats per minute (bpm) using the pulse? Count the number of beats in 15 seconds and multiply by four Count the number of beats in 30 seconds and multiply by two Count the number of beats in 10 seconds and multiply by six Count the number of beats in 20 seconds and multiply by three
