ACLS QUESTION AND VERIFIED
ANSWERS
Sinus bradycardia rate
Treatment - ANSWER>><60 may or may not be needed (ie. BP) - atropine,
pacing, epinephrine, dopamine
Sinus tachycardia rate
Treatment - ANSWER>>>100
• Normal response to stress
• Infection, hypoxemia, hypovolemia, MI, drugs
• Can impair cardiac output
Atrial fibrillation
Treatment - ANSWER>>-P waves not present - atria are not depolarizing - they are
fibrillating - chaotic wavy baseline
QRS looks normal but is irregular (irregular ventricular reponse
-Treat with anticoagulation, digoxin, beta blockers - may need to cardiovert
Ventricular fibrillation (V-fib)
2.TREATMENT - ANSWER>>=P waves and PR Interval are absent
=QRS complexes are absent
-Electrical activity consists of low (fine) or high (coarse) amplitude undulations
from the baseline that vary in shape
-There is no rate
-There is no pulse
2. EPI 2-3MIN
AMIODARONE- 300mg
, 1. Ventricular tachycardia (V-tach)
2. Treatment - ANSWER>>-No P waves
P-R Interval can't be measured
-QRS complexes are wide and bizarre looking
=QRS may be similar (unifocal)
• QRS complexes may vary (multifocal)
-Rate 150-250 per minute
-May occur with or without a pulse
2.
-Deliver unsynchronized shock 120-200 joules
-Epinephrine 1 mg IV/IO (1:10,000) Q3-5 minutes during compressions
-Amiodarone 300 mg IV/IO, 2nd dose 150 mg in 5-10 min - if conversion set up
drip
OR
-Lidocaine 1.0-1.5 mg/kg IV/IO, 2nd and 3rd doses .5 to .75 mg/kg in 5-10 min (x 2
ifneeded) MAX 3 mg/kg - if conversion set up drip
-optimize oxygenation and ventilation, treat hypotension, treat STEMI if needed,
fluid bolus
monomorphic vs. polymorphic v tach - ANSWER>>
SVT - ANSWER>>
Ist Degree Heart Block - ANSWER>>PR Interval is longer than .20 sec but are
generally equal
This rhythm looks a lot like normal sinus rhythm, but it has a subtle secret. The PR
intervals will be prolonged ( >0.20 seconds) regularly throughout the rhythm
