Inclusion Criteria:

  • Patients with symptomatic permanent AF (>6 months) for which cardioversion is not considered and resting ventricular rate > or equal 80 bpm at screening measured on a 6-seconds rhythm strip,

Exclusion Criteria:

  • Unstable angina pectoris, recent myocardial infarction or history of torsades de pointes
  • Third degree atrioventricular block at the screening ECG or significant sinus node disease without a permanent pacemaker implanted
  • Clinically overt congestive heart failure at randomization
  • Patients treated with amiodarone, other antiarrhythmic drugs or previous participation in this trial or in other dronedarone trials or taking an investigational drug
  • Clinically relevant haematologic, hepatic, gastro-intestinal, renal, pulmonary, endocrinologic or psychiatric disease
  • Pregnant and/or breastfeeding women or women of child-bearing potential with no adequate birth control
