Explain Antiarrhythmic Drugs?

Amiodarone may be considered in VT/VF that is refractory to shock. It might be given if the third shock is not successful. The dose is 300 mg IV in 20 mls 5 per cent dextrose over a period of 15 minutes. A additional bolus of 150 mg may be given for refractory VT/VF, followed by an infusion, initially of 1.0 mg/mt for six hours, and then reduced to 0.5 mg/mt, to a maximum dose of 2.0 G.
Lignocaine is an alternative in this situation if amiodarone is not available.
