Which situation is appropriate for a nurse to perform synchronized cardioversion? Select all that apply.

Unstable ventricular tachycardia (patient has a pulse) Symptomatic atrial tachydysrhythmias (SVT, afib, aflutter) Rationale Stable atrial tachydysrhythmias and unstable ventricular tachydysrhythmias should be treated with synchronized cardioversion.

The shock works during the cardiac depolarization; therefore, this intervention would not work for patients with ventricular fibrillation, asystole, or standstill. This method is also not performed for patients with premature ventricular contractions. p. 681
