EKG rhythms || A+ Graded Already.

Normal Sinus Rhythm correct answers 60-100 bpm all complexes normal and evenly spaced (P, QRS, T) Sinus Arrest correct answers - SA node doesn't fire - notice absence of P-wave for a complete cycle (a missed cycle) Sinus arrhythmia correct answers 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 correct answers 60 normal sinus rhythm Sinus Tachycardia correct answers 100 (100-150) normal sinus rhythm Wandering atrial pacemaker correct answers 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 correct answers P generally smaller than T MAT (multifocal atrial tachy) correct answers - impulse originates at diff places in atria so P waves diff and intervals might not be consistent - assoc w/ severe pulm dz Atrial Fibrillation correct answers 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 correct answers 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 correct answers retrograde atrial depolarization P' is inverted Junctional rhythm correct answers 40-60 Regular! -impulse from AV node w/ retro/antegrade transmission - P wave often inverted/buried/follow QRS
