STARN EKG EXAM QUESTIONS AND 100%
CORRECT ANSWERS
sinus rhythms originate from - Answer SA node
SA node pace - Answer 60-100 bpm
sinus bradycardia rate - Answer 60-100 bpm
sinus tachycardia rate - Answer 100+bpm
sinus dysrhythmia features - Answer speeds up and slows down in cyclical manner
- sometimes this cycle follows the pattern of breathing
- HR may increase during inspiration and decrease during expiration (opposite when pt
is vented d/t + pressure of vent)
sinus arrest-Ans. cessation of heartbeat. When SA node briefly stops firing
What medication can cause sinus bradycardia-Ans. beta blockers
What medication to give for sinus bradycardia-Ans. atropine
Sinus dysrhythmia may occur as a result of:-Ans. digitalis (digoxin), morphine,
conditions w/ increased ICP
Atrial dysrhythmias originate in-Ans. atrial tissue or internodal pathways
, wandering atrial pacemaker characteristics - Answer pacemaker shifts between SA
node, atria, and/or AV junction
- P waves appear differently each time
wandering atrial pacemaker causes - Answer - normal finding in children, older adults,
and athletes
- drug toxicity (digitalis)
premature atrial complex - Answer comes a little bit early compared to rest of P waves
HAS UNDERLYING RHYTHM
do you count PACs as an actual perfusing beat? - Answer yes
what to do if pt has frequent PACs - Answer assess pt and lab values
- may be an early sign of electrolyte imbalance or CHF
atrial tachycardia rate - Answer 150-250 bpm
supraventricular tachycardia characteristics - Answer originates from above the
ventricles but P waves not distinct
what to do if SVT occurs - Answer - activate rapid response
- vasovagal maneuvers
- adenosine
- synchronized cardioversion
atrial flutter rate - Answer 250-350 bpm
