Overview
Chemical cardioversion refers to restoring the heart's rhythm to normal through pharmacological agents such as amiodarone, propafenone, and flecainide. Such medications work by altering the heart’s electrical properties to suppress the abnormal heart rhythms and restore a normal rhythm, and can be administered orally or intravenously. The treatment can be carried either in an in-patient or out-patient setting.
Atrial fibrillation pharmacological cardioversion
- Patient's preferences, presence of other comorbidities, adverse effects of the medications and chance of atrial fibrillation recurrence should be noted when pharmacologica cardioversion for long term is considered. [1]
- The following are some of the available pharmacological cardioversions for atrial fibrillation:[1]
- Class 1c antiarrhythmic drugs such as flecainide or propafenone should be avoided in atrial fibrillation patients with previous history of ischemia or structural heart disease.[1]
- If long term pharmacological cardioversion has been decided for the patient, a standard beta blocker (a beta blocker other than sotalol) could be considered as a first line treatment option. (unless there is a contraindication) [1]
- Amiodarone could be a wise choice for atrial fibrillation patients with concurrent left ventricular impairment or heart failure.
- If the patient is experiencing few symptoms or only experiences symptoms when there is a known trigger (such as alcohol and caffein) or if the atrial fibrillation occurs as infrequent paroxysms no treatment strategy could be considered.
- Even in electrical cardioversion candidates a 4 week period of amiodarone treatment before electrical cardioversion and up to 1 year period of amiodarone therapy after electrical cardioversion is required.[1]
Pill-in-the-Pocket Strategy
- This method only could be considered for atrial fibrillation patients with few symptoms or if the atrial fibrillation occurs as infrequent paroxysms. This method also could be selected in patients who only experience symptoms when there is a known trigger (such as alcohol and caffein). [1]
- In this strategy patients take an antiarrhythmic agent only when they have an episode of atrial fibrillation.
- Pill-in-the-pocket strategy could be selected in the presence of the following for the patients with paroxysmal atrial fibrillation:[1]
- No history of left ventricular dysfunction
- No history of ischemia or valvular heart disease
- In the presence of infrequent paroxysms with minimal symptoms
- Systolic blood pressure greater than 100 mmHg
- Resting heart rate more than 70
- Ability of patients in being educated regard how and when the pill should be taken

Rhythm Control
Electrical and Pharmacological Cardioversion of AF and Atrial Flutter
Pharmacological Cardioversion
| Class I |
| "1. Flecainide, dofetilide, propafenone, and intravenous ibutilide are useful for pharmacological cardioversion of AF or atrial flutter provided contraindications to the selected drug are absent. (Level of Evidence: A) " |
| Class III: Harm |
| "1. Dofetilide therapy should not be initiated out of hospital owing to the risk of excessive QT prolongation that can cause torsades de pointes. (Level of Evidence: B) " |
| Class IIa |
| "1. Administration of oral amiodarone is a reasonable option for pharmacological cardioversion of AF. (Level of Evidence: A) " |
| "2. Propafenone or flecainide (“pill-in-the-pocket”) in addition to a beta blocker or nondihydropyridine calcium channel antagonist is reasonable to terminate AF outside the hospital once this treatment has been observed to be safe in a monitored setting for selected patients. (Level of Evidence: B) " |
