1. sinus rhythms originate from <Ans> SA node
2. SA node pace <Ans> 60-100 bpm
3. sinus bradycardia rate <Ans> 60-100 bpm
4. sinus tachycardia rate <Ans> 100+bpm
5. sinus dysrhythmia features <Ans> 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)
6. sinus arrest <Ans> pause in heartbeat. occurs when SA node temporarily stop
firing
7. what medication can cause sinus bradycardia <Ans> beta blockers
8. what medication to give for sinus bradycardia <Ans> atropine
9. sinus dysrhythmia may occur as a result of <Ans> <Ans> digitalis
(digoxin), morphine, conditions w/ increased ICP
10. atrial dysrhythmias originate in <Ans> atrial tissue or internodal pathways
11. wandering atrial pacemaker characteristics <Ans> pacemaker shifts
between SA node, atria, and/or AV junction
- P waves look different every time
12. wandering atrial pacemaker causes <Ans> - normal finding in children, older
adults, and athletes
- drug toxicity (digitalis)
13. premature atrial complex <Ans> comes a little bit early compared to rest of
P waves HAS UNDERLYING RHYTHM
1/6
, 14. do you count PACs as an actual perfusing beat? <Ans> yes
15. what to do if pt has frequent PACs <Ans> assess pt and lab values
- possible early indicator of electrolyte imbalance or CHF
16. atrial tachycardia rate <Ans> 150-250 bpm
17. supraventricular tachycardia features <Ans> arises from above the
ventricles but P waves not well defined
18. what to do in case of SVT <Ans> - call rapid response
- vasovagal maneuvers
- adenosine
- synchronized cardioversion
19. atrial flutter rate <Ans> 250-350 bpm
20. atrial flutter features <Ans> sawtooth waves!
- make sure to note conduction ratio
21. atrial fibrillation features <Ans> irregularly irregular
- "F" waves
- no rhythm and no P waves
