pulse <150/min? YES -> immediate cardioversion generally not needed

pulse >150/min? YES -> check O2 saturation, IV access, suction and airway equipment available

whenever possible premedicate for cardioversion

polymorphic v tach? YES -> treat as v fib (defibrillate x3 (200, 200-300, 360 J))

Paroxysmal Superventricular Tachycardia (PSVT) or atrial flutter? YES -> start with low power synchronized cardioversion (50 J) and proceed to higher settings as needed (100, 200, 300, 360 J)
