Brief summary
The purpose of this study is to determine whether or not the reduction of Atrial Fibrillation (AF) by the AF Suppression algorithm halts or reverses the electrical remodeling that has already begun in AF Patients
Interventions
This study aims at determining whether or not the reduction of Atrial Fibrillation (AF) by the AF suppression algorithm halts or reverses electrical remodeling that has already begun in AF patients. The algorithm provides stimulation that controls the atrial rate and rhythm minimising ectopic beats, long-short cycles and dispersion of refractoriness. It does this by monitoring the intrinsic atrial rhythm and then adapting the pacing rate slightly above the intrinsic rhythm to help ensure a high percentage of atrial pacing that is dynamically tailored to the patients rate variations. From the point of implant the device is constantly monitoring and correcting the pacing of the heart. The duration of the study is 6 months, the device will remain implanted and continue to treat the patient: Changing of the status of the AF supression algorithm being 'ON' or 'OFF' is at the discretion of the physician.
