ResumoBackground: atrial fibrillation (AF) is the most common arrhythmia in clinical practice.Drug therapy has only a limited effect on suppression of AF.Preventive Pacing Algorithms and Antitachy Pacing strategies (ATP) are increasingly used in patients with sinus node disease and paroxysmal atrial arrhythmias.Methods: in 40 patients with sick sinus syndrome and a class I/II indication for pacemaker implantation and documented paroxysmal or persistent atrial arrhythmias a Medtronic AT-500 pacemaker was implanted.Patients at stable antiarrhythmic medication and with documented AF/AT in the pacemaker memory 6-8 weeks after hospital discharge were eligible for the study.Pacemakers were programmed in DDDR-mode with all preventive algorithms and ATP off.After 3 months all preventive algorithms and ATP-therapies were activated for another 3 months period.Results: activating the preventive pacing algorithms resulted in a decrease of the median AF-burden by 33%.ATP was successful in 53% of 12776 treated episodes.Conclusion: AF-burden can be reduced by preventive pacing algorithms in patients with sick sinus syndrome and paroxysmal atrial arrhythmias.ATP therapies are effective in terminating atrial tachyarrhythmias.
