ECHELON CLASS EXAM QUESTIONS
& VERIFIED ANSWERS RATED 100%
CORRECT
sinus bradycardia - Correct Answer ✔✔ -less than 60 beats per minute
-P wave in front of every QRS
-PR--0.12 to 0.20
-QRS less than 0.12
-if symptomatic--atropine, pacemaker
sinus tachycardia - Correct Answer ✔✔ -treat underlying cause (fever, pain, etc.)
Sinus Arrhythmia - Correct Answer ✔✔ irregular with breathing--HR increases with
inspiration and decreases with expiration
-only treat if hemodynamically compromised--atropine
SA block - Correct Answer ✔✔ -dropped interval/pause
-if hemodynamically compromised--atropine, permanent pacemaker
sinus arrest - Correct Answer ✔✔ - SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
-no treatment if episodes are transient otherwise temporary pacing or atropine
Premature Atrial Contraction (PAC) - Correct Answer ✔✔ if symptomatic--digitalis, beta
blockers, antiarrhythmics
atrial flutter - Correct Answer ✔✔ -Sawtooth pattern
-250 to 350 beats
-PRI cant determine**
-QRS less than .12
-need to control ventricular rate and convert the rhythm/anticoagulate
a fib - Correct Answer ✔✔ -no p wave
-PRI cant measure**
-QRS les than 0.12
-rate control and anti coag
SVT - Correct Answer ✔✔ -regular rate and rhythm
-P wave not visible**
-PRI 0.12-0.20**
-QRS less than 0.12
-tx: vagal simulation
