About this trial
This is an interventional treatment trial for Atrial Fibrillation focused on measuring Atrial Fibrillation, Atrial Flutter, Arrhythmia, Anti-Arrhythmia agents
Eligibility Criteria
Inclusion Criteria: Patients of either sex aged 21 years or more, in sinus rhythm for at least 1 hour at the time of randomisation and with at least one ECG-documented AF/AFL episode in the last 3 months. Exclusion Criteria: MAIN CRITERIA (non-exhaustive list, see protocol for details): Women of childbearing potential without adequate birth control, Pregnant women, Breastfeeding women, Congestive heart failure NYHA class III or IV, Conditions which increase the risk of severe antiarrhythmic drug side effects, Severe associated conditions.

Outcomes
Primary Outcome Measures
The primary endpoint of the study is the time from randomisation to first documented AF/AFL recurrence
Secondary Outcome Measures
- AF/AFL related symptoms collected at the time of ECG/TTEM recording,
- mean ventricular rate during AF/AFL at first recorded AF/AFL recurrence (12-lead ECG or TTEM)
- time from presumed study drug near steady state defined as D5 midnight to first documented AF/AFL recurrence as indicated by ECG/TTEM recording.

5. Study Description
Brief Summary
To assess the efficacy of dronedarone versus placebo for the maintenance of normal sinus rhythm after electrical, pharmacological or spontaneous conversion of atrial fibrillation/atrial flutter (AF/AFL).
To assess the efficacy of dronedarone versus placebo on ventricular rate control in case of AF/AFL recurrence.
To assess the efficacy of dronedarone versus placebo on AF/AFL-related symptoms.
Detailed Description
This is a double-blind, parallel arm, placebo-controlled, multicentre, multinational, phase III study.
To be eligible, patients must be in normal sinus rhythm at randomisation and must have an ECG-documented history of recent AF/AFL reverted to normal sinus rhythm by electrical, pharmacological or spontaneous conversion.
