Question 1
An irregular rhythm is one in which
◦ the R-R intervals vary "all over the place."
◦ there are premature beats or pauses that interrupt the otherwise regular rhythm.
◦ the QRS complexes do not look alike.
◦ the R-R intervals vary by only one or two little blocks.
Question 2
Regardless of the method used, what are you doing when you calculate heart rate?
◦ Counting the number of irregular blocks in a minute-long rhythm strip
◦ Counting the number of QRS complexes in a minute-long rhythm strip
◦ Counting the number of premature beats or pauses in a minute-long rhythm strip
◦ Counting the number of P waves in a minute-long rhythm strip
