ACLS review

161.  Name four rhythms that may be treated with synchronized cardioversion.

Unstable SVT

Unstable atrial fibrillation

Unstable atrial flutter

Unstable monomorphic VT

162. What is the appropriate joule setting when performing cardioversion on a patient with unstable VT, A fib, A flutter, or SVT?

Monomorphic VT 100 J

A fib 120-200 J

A flutter 50-100 J

SVT 50-100 J

163.  What are some characteristics of reentry tachycardia?

A tachycardia that is caused by an abnormal rhythm circuit that allows a wave of depolarization to repeatedly travel in a circle in cardiac tissue.

The QRS complex is narrow (<0.12 second) or wide (broad) if a preexisting bundle branch block is present.

These arrhythmias have characteristic abrupt onset and termination.

164.  What are some characteristics of automatic tachycardias?

These arrhythmias are not due to a circulating circuit but to an excited automatic focus

These arrhythmias have a more gradual onset and termination

These automatic arrhythmias include ectopic atrial tachycardia, MAT, and junctional tachycardia

These arrhythmias are not responsive to cardioversion

165.  What are the preferred initial therapeutic choices for the termination of stable PSVT?

Vagal maneuvers and adenosine
