Primary Outcome(s)

Primary end point(s): Change from baseline in atrial fibrillation burden (both percent change and absolute change).

Timepoint(s) of evaluation of this end point: 12 weeks

Secondary Objective: To evaluate the effect of ranolazine and of dronedarone when given alone and in combination at different dose levels on:
— Atrial fibrillation burden for each visit period
— Number of atrial fibrillation episodes, duration of atrial fibrillation episodes, and ventricular rate during atrial fibrillation episodes
— Ventricular rate over 12-weeks of treatment and for each visit period
— Percentage of ventricular pacing
— Percentage of atrial pacing
— Incidence of persistent atrial fibrillation
— Incidence of electrical cardioversion
— Incidence of symptomatic episodes

To determine the percentage of subjects who have = 30% (= 50%) reduction from baseline in AFB

To determine the percentage of subjects who have total duration of AF episodes = 5.5 hours per day at any point during the treatment period

Main Objective: To evaluate the effect of ranolazine and of low dose dronedarone when given alone and in combination at different dose levels on AFB over 12 weeks of treatment

AFB is defined as the total time a subject is in atrial tachycardia/atrial fibrillation (AT/AF) expressed as a percentage of total recording time.

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: 4, 8 and 12 weeks

Secondary end point(s): 1. Change from baseline in atrial fibrillation burden for each visit period 2. Change from baseline in number of AF episodes, duration of AF episodes, and average ventricular rate for each AF episode
3. Change from baseline in ventricular rate for each visit period
4. Percent ventricular pacing for each visit period
5. Percent atrial pacing
6. Incidence of persistent atrial fibrillation
7. Incidence of electrical cardioversion
8. Incidence of symptomatic episodes
