1. Normal Sinus 60-100 bpm
Rhythm all complexes normal and evenly spaced (P, QRS, T)
2. Sinus Arrest - SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
3. Sinus arrhythmia all complexes normal but rhythmically irreg
- normal finding (esp in young pts) that has to do with breathing (rate: inhale-in-
crease, exhale-decrease)
4. Sinus Bradycar- <60
dia normal sinus rhythm
5. Sinus Tachycar- >100 (100-150)
dia normal sinus rhythm
6. Wandering atrial Hint: try never to pick this
pacemaker - impulse originate from varying points in atria
- variation in P wave contour, PR-I, PP-I and thus RR-I
7. P wave vs T wave P generally smaller than T
8.

MAT (multifocal - impulse originates at diff places in atria so P waves diff and intervals might not
atrial tachy) be consistent
- assoc w/ severe pulm dz
9. Atrial Fibrillation A: 350-450 (atria quivering)
- irreg-irreg rhythm (R-RI=irreg)
**unsure/no P-wave (non-distinguishable)**
- irreg rhythm BUT reg QRS!
Danger: increase the risk of thromboemoblic events don't convert unless occurring
less than 48 hrs, if don't know pt need to be put on thrombolytics)
10. Atrial Flutter A: 250-350
- "saw tooth" p-waves
- a continuous rapid sequence of atrial complexes from a single rapid-firing atrial
focus
(hint: if see 2 P waves and QRS think A Flutter)
11. Junctional Escape retrograde atrial depolarization
beats P' is inverted
12. Junctional 40-60 Regular!
rhythm -impulse from AV node w/ retro/antegrade transmission
- P wave often inverted/buried/follow QRS
- slow rate
- narrow QRS (not wide like ventricular)
