Fill in the blank: The fifth step in identifying components of the rhythm is ________.

Back

QRS duration and morphology

Front

What is the first step in determining a ventricular rhythm?

Back

Measure a R-R interval

Front

What is the normal range for the PR interval in seconds? Options: 0.10-0.18 s, 0.12-0.20 s, 0.15-0.25 s, 0.20-0.30 s

Back

0.12-0.20 s

Front

Why should the PR interval be measured to the closest 0.02 s or 20 ms?

Back

Because the human eye cannot determine 0.01 s
