Many Differences..: Be more specific, if you would. Both drugs are used effectively for the arrhythmias that occur during an arrest. But their mechanisms of action, effects on heart performance, time to onset of "action, " and appropriateness as a first line of defense differ widely. If an individual has an implantable defibrillator device in place this would also affect the decision to use one or the other.

Amio preferred: Lidocaine is no longer listed in acls protocols because of reduced efficacy and potential for toxicity. Amiodarone is the preferred drug.
