STARN EKG – Questions & Answers (Graded A+)Sinus rhythms originate from ✔️Ans - SA node
SA node pace ✔️Ans - 60-100 bpm
Sinus bradycardia rate ✔️Ans - 60-100 bpm
Sinus tachycardia rate ✔️Ans - 100+bpm
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)
Sinus arrest ✔️Ans - pause in heartbeat. occurs when SA node
temporarily 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 ✔️Ans - pacemaker shifts
between SA node, atria, and/or AV junction

wandering atrial pacemaker causes ✔️Ans - - normal finding in children,
older adults, and athletes

HAS UNDERLYING RHYTHM

atrial flutter rate ✔️Ans - 250-350 bpm
atrial flutter features ✔️Ans - sawtooth waves!
- make sure to note conduction ratio
atrial fibrillation features ✔️Ans - irregularly irregular
- "F" waves
- no rhythm and no P waves
atrial fibrillation is dangerous because ✔️Ans - patients may develop intra
atrial emboli as blood pools in the atrial chambers
- pt at risk for stroke/PE
junctional dysrhythmias originate in ✔️Ans - AV junction (area around AV
node and bundle of His)
junctional dysrhythmia key characteristics ✔️Ans - P waves inverted or
absent
regular QRS
