In the Adult Cardiac Arrest algorithm, we should administer an antiarrhythmic medication to patients in V-Fib or pulseless ventricular tachycardia approximately two minutes after the first dose of epinephrine. The two first-line ACLS antiarrhythmics that are generally used are Amiodarone and Lidocaine. Review of Lidocaine dosing and administration to patients in persistent V-Fib or pulseless V-Tach. Review of Amiodarone dosing and administration to patients in persistent V-Fib or pulseless V-Tach. Use of antiarrhythmic infusions post-cardiac arrest to suppress ventricular ectopy.  Amiodarone use & dosing for stable patients in V-Tach with a pulse.
