If a rhythm is IRREGULAR, the best way to determine rate is to:
A)count the number of large squares between two R waves and divide that into 300.
B)use a rate meter.
C)count the number of QRS complexes in a 6- sec.strip and multiply by 10.
D)count the number of small squares between two R waves and divide that into 1500.

Counting the number of QRS complexes in a 6-sec strip and multiplying by 10 is the best way to determine rate in an irregular rhythm because it accounts for the variability between R waves. Counting large or small squares assumes a regular rhythm, and a rate meter may not accurately detect the rate in an irregular rhythm.
