Describe the methods used to calculate the heart rate of a rhythm strip.
Using a caliber, measure the distance between two R waves. Then, keeping that measurement on the caliber, measure each R to R interval to make sure they are all equal.
If all the QRS complexes are of equal distance between each other, measure the number of small boxes between the R waves and divide this number into 1500.
If the rhythm is ...
