First step in assessing an ECG strip
count the number of R waves
count the number of P waves
make sure that you are assessing a 6 second strip
count the number of large boxes
How do you decide if an ECG strip rate is regular?
count the P-P interval
count the R-R interval
count the pr interval
count the QR interval
Which method for assessing ECG rate is best for an irregular rhythm?
1500 method
6 second method

venticle
atria
valves
