- Shock: Biphasic, 120 to 200 J; monophasic, 360 J.
- CPR: 2 min—obtain IV/IO access—reassess rhythm.
- Shock: Biphasic: 120 to 200 J; monophasic: 360 J.
- CPR: 2 min—Epinephrine: 1 mg IV/IO every 3 to 5 min. Consider advanced airway, capnography, and reassess rhythm.
- Shock: Biphasic: 120 to 200 J; monophasic: 360 J.
- CPR: 2 min—Amiodarone: 300 mg IV/IO. May repeat (if needed) at 150 mg. Treat reversible causes, and reassess rhythm. Note: If amiodarone is unavailable, give lidocaine: 1.0 to 1.5 mg/kg IV/IO, repeated 0.5 to 0.75 mg/kg every 5 to 10 min, maximum three doses or 3 mg/kg.
- For torsade de pointes, give magnesium: 1 to 2 g (diluted in 10 mL) IV/IO.
