EMT EKG Rhythms
Normal Sinus Rhythm - answer60-100 bpm
all complexes normal and evenly spaced (P, QRS, T)
Sinus Bradycardia - answer<60
normal sinus rhythm
Sinus Tachycardia - answer>100 (100-150)
normal sinus rhythm
P wave vs T wave - answerP generally smaller than T
Asystole - answer- dead
- no electrical activity, only straight line (no rate/pulse)
A dire form of cardiac arrest in which the heart stops beating -- there is no systole -- and
there is no electrical activity in the heart. The heart is at a total standstill.
Premature ventricular contractions (PVC's) - answer*Wide QRS*
- may be unifocal or multifocal
- will have compensatory pause
- irreg rythm PVCs may be bigeminy, trigeminy, or quadrigeminy
- "run of" PVCS
- 3+ PVCs = Vtach!
Ventricular tachycardia - answer150-250 (>120 from onysko)
- ventricle irritated and moving fast
- rapid, bizarre, wide QRS complexes
- 1 large QRS after another!
(in vtach pt may not have pulse)
Ventricular Fibrillation - answer350-450
- "chaotic"
- mult vent foci rapidly discharging -> erratic vent rhythm
- no identifiable waves
- RESPOND IMMEDIATELY!
- no pulse or perfusion, pt=dead
anterior wall - answerV1, V2, V3, V4
- occlusion of anterior descending coronary artery
Anteroseptal region - answerV1, V2
