Brief Summary:
This clinical investigation is a prospective, single-blinded, randomized trial. The primary objective concerns the safety and effectiveness of the AAIsafeR mode with the preventive algorithms.

Condition or disease Intervention/treatment Phase
Sinus Node Dysfunction Brady Tachy Syndrome Device: PACEMAKER SYMPHONY 2550 Phase 4

Detailed Description:
In this study, patients are randomized to DDD mode, AAIsafeR mode, or AAIsafeR mode plus atrial arrhythmia preventive algorithms. The atrial arrhythmia (AA) burden serves as the primary measure of effectiveness.
