Calculating Heart Rate on EKG
The 1500 Method: Count the number of small boxes between two successive R waves and divide
this number into 1500 to obtain heart rate. This works well for faster heart rates.
The 300 Method: Count the number of large boxes between 2 successive R waves and divide by
300 to obtain heart rate.
Six Second Strip Method: Count the number of R Waves in a six second strip then multiple by 10
to obtain heart rate.
