Identify the appropriate electrical intervention for the following EKG rhythms

1.

a.  Unsynchronized shock at 120-200J
b.  Electrical intervention inappropriate for this rhythm
c.  Synchronized cardioversion at 50 mA
d.  Standby demand pacing at 60 bpm

2.

PEA rhythm

a.  Defibrillation at 360 J (monophasic)
b.  Deliver an asynchronous shock at 200 J (biphasic)
c.  Electrical intervention inappropriate for this rhythm
d.  Epicardial pacing at 100 J

3.

a.  Cardioversion with 50 J
b.  Unsynchronized shock at 120-200 J
c.  Electrical intervention is not appropriate for this rhythm
d.  Fixed rate overdrive pacing at 120 bpm

4.

Pulseless arrest

a.  Demand pacing at 60 bpm
b.  Transcutanous pacing with 2-4J/kg
c.  Defibrillation 120-200 J (biphasic)
d.  Cardioversion 100 J


5.

Unstable polymorphic VT

a.  Fixed rate pacing at 60 bpm
b.  Electrical intervention inappropriate for this rhythm
c.  Unsynchronized shock 120-200 J (biphasic)
d.  Cardioversion 100 J, then 200 J for a refractory rhythm
