  Purpose

Primary Objective:

- Evaluate the rate of Atrial Fibrillation (AF) recurrences one month after randomization according to different timings of initiation of dronedarone.

Secondary Objective:

  • Evaluate the rate of AF recurrences two months after randomization.
  • Assess the safety of the change from amiodarone to dronedarone
  • Assess dronedarone safety
  • Explore dronedarone and its active metabolite plasma level (in a subset of countries)
  • Explore potential Pharmacokinetic (PK) interaction between dronedarone and amiodarone (in a subset of countries)

Primary Outcome Measures:
  • AF recurrences [ Time Frame: one month after randomization ] [ Designated as safety issue: No ]
    two consecutives 12-lead ECG or Trans-Telephonic ECG monitoring (TTEM) approximatively 10 minutes apart and both showing AF


Secondary Outcome Measures:
  • AF recurrences [ Time Frame: two months after randomization ] [ Designated as safety issue: No ]
  • Symptomatic bradycardia [ Time Frame: two months after randomization ] [ Designated as safety issue: No ]
    Heart rate at rest < 50 beats per minute

  • Tachycardia [ Time Frame: two months after randomization ] [ Designated as safety issue: No ]
    Heart rate at rest > 120 beats per minute

  • Dronedarone and amiodarone concentrations in plasma [ Time Frame: 3 hours, 1 week, 2 weeks and 4 weeks after 1st Dronedarone intake ] [ Designated as safety issue: No ]
    Limited to a subset of countries
