These drugs are used for the treatment of ventricular dysrhythmias. Amiodarone may also be useful in the treatment of atrial fibrillation.

Amiodarone (Cordarone)

Class III antiarrhythmic. May inhibit AV conduction and sinus node function. Prolongs action potential and refractory period in myocardium and inhibits adrenergic stimulation. Effective in converting atrial fibrillation and flutter to sinus rhythm and in suppressing recurrence. Before administration, control ventricular rate with another agent (eg, calcium channel blocker). Drug of choice for life-threatening ventricular arrhythmias, except for disorders of prolonged repolarization (eg, long-QT syndrome [LQTS]).

Lidocaine (Dilocaine, Xylocaine)

Second-line drug for VT or VF. Class IB antiarrhythmic that increases electrical stimulation threshold of ventricle, suppressing automaticity of conduction through the tissue.
