VF or pulseless VT refractory to electrical countershocks and epinephrine.

Stable VT or stable wide-complex tachycardia of uncertain origin: repeat doses of half the original dose

If lidocaine successfully converts the VF/VT; begin a continuous infusion @ 2-4mg/min (1mg=15cc on pump)

* Use 2-2.5 times the IV dose when given via ET tube; followed by 10 ml saline flush

* If toxic symptoms develop (slurred speech, altered LOC, muscle twitching and seizures), stop the drug or reduce the dose

* Do NOT give this drug if PVCs occur with bradycardia or escape rhythm.

* No longer recommended for VF/VT prophylaxis in acute MI

* Suppresses ventricular arrhythmias and elevates the fibrillation threshold (less likely to occur)
