1. 1. determining rate what 5 things can help determine
2. determining regularity rhythm
3. assessing P waves
4. assessing QRS complex
5. assessing PR intervals

2. p wave, QRS waves, P/QRS when trying to determine rhythm, look
at the pattern of the ________ rela-
tive to the ________ and how each
_____/_____ compares to previous
ones in the strip

3. 60 - 100bpm Normal Sinus Rhythm (NSR) -- rate

4. regular Normal Sinus Rhythm (NSR) -- regular-
ity

5. 1:1 ratio with each QRS, normal size/duration, Normal Sinus Rhythm (NSR) -- P wave
same morphology for every P wave

6. narrow (unless BBB is present) Normal Sinus Rhythm (NSR) -- QRS
complex

7. 0.12 - 0.20 seconds Normal Sinus Rhythm (NSR) -- PR inter-
val duration

8. <60bpm Sinus Bradycardia -- rate

9. regular Sinus Bradycardia -- regularity

10. 1:1 ratio with QRS, normal size/duration, Sinus Bradycardia -- P wave
same morphology for every P wave

11. narrow (unless BBB is present) Sinus Bradycardia -- QRS complex
