Dear Editor,

I thank the author for the supportive comments and criticisms to our article "anaphylaxis during intravenous administration of amiodarone". [1] A trial fibrillation (AF) is the most common chronic cardiac arrhythmia occurring in 1-2% of the general population. [2],[3] AF is an independent risk factor for stroke; in fact, it increases the risk of stroke approximately fivefold. [4] In patients with AF, major mortality and morbidity are secondary to stroke and systemic embolism. The goals of management of acute AF are to relieve patients' symptoms and to prevent thromboembolic complication especially stroke. Clinical evaluation of AF should include determination of the estimation of stroke risk and search for conditions that predispose to AF and for complications of the arrhythmia. [2],[4] Many episodes of AF terminate spontaneously within the 1 st h or days. Medical cardioversion is indicated in patients with recent-onset AF who remain symptomatic despite adequate rate control. Pharmacological cardioversion may be initiated by a bolus administration of an antiarrhythmic drug. The conversion rate with antiarrhythmic drugs is lower than with direct current cardioversion, but does not require conscious sedation or anesthesia and may facilitate the choice of antiarrhythmic drug therapy to prevent recurrent AF. Several agents are available for pharmacological cardioversion. [4],[5] The Task Force the European Society of Cardiology [4] for the Management of AF recommends intravenous flecainide or propafenone for cardioversion of recent-onset AF when pharmacological cardioversion is preferred and there is no structural heart disease (Class I recommendation). In patients with recent-onset AF and structural heart disease, intravenous amiodarone is recommended (Class I recommendation). Digoxin, verapamil, sotalol, metoprolol, other beta-blocking agents and ajmaline are ineffective in converting recent onset AF to sinus rhythm and are not recommended (Class III recommendation). [4] Unfortunately, we did not have intravenous flecainide, propafenone or esmolol. Our patient was symptomatic even after rate control with administration of diltiazem. Therefore, we decided to administer amiodarone. Medical cardioversion was indicated in our patient, as she remained symptomatic even after adequate rate control. Therefore, amiodarone was administered for pharmacological cardioversion. It should be noted that The Task Force of the European Society of Cardiology has not considered metoprolol an effective drug for converting AF to sinus rhythm and not recommended. [4]
