<P> Lidocaine is also the most important class - 1b antiarrhythmic drug ; it is used intravenously for the treatment of ventricular arrhythmias ( for acute myocardial infarction , digoxin poisoning , cardioversion , or cardiac catheterization ) if amiodarone is not available or contraindicated . Lidocaine should be given for this indication after defibrillation , CPR , and vasopressors have been initiated . A routine preventative dose is no longer recommended after a myocardial infarction as the overall benefit is not convincing . </P>
