COMPLETE QUESTIONS AND ANSWERS
PRACTICE SOLUTION VERIFIED
◉ Normal Sinus Rhythm. Answer: 60-100 bpm
all complexes normal and evenly spaced (P, QRS, T)
◉ Sinus Arrest. Answer: - SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
◉ Sinus arrhythmia. Answer: all complexes normal but rhythmically
irreg
- normal finding (esp in young pts) that has to do with breathing (rate:
inhale-increase, exhale-decrease)
◉ Sinus Bradycardia. Answer: <60
normal sinus rhythm
◉ Sinus Tachycardia. Answer: >100 (100-150)
normal sinus rhythm
◉ Wandering atrial pacemaker. Answer: Hint: try never to pick this
, - impulse originate from varying points in atria
- variation in P wave contour, PR-I, PP-I and thus RR-I
◉ P wave vs T wave. Answer: P generally smaller than T
◉ MAT (multifocal atrial tachy). Answer: - impulse originates at diff
places in atria so P waves diff and intervals might not be consistent
- assoc w/ severe pulm dz
◉ Atrial Fibrillation. Answer: 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)
◉ Atrial Flutter. Answer: 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)
◉ Junctional Escape beats. Answer: retrograde atrial depolarization
P' is inverted
