Study Arms:
- Active group - CLS ON (Type: EXPERIMENTAL): Device will be programmed in a dual-chamber DDD pacing mode with the Closed Loop Stimulation (CLS) function ON; Intervention: DDD+CLS
- Control group - CLS OFF (Type: ACTIVE_COMPARATOR): Device will be programmed in a dual-chamber DDD(R) pacing mode with the Closed Loop Stimulation (CLS) function OFF

Based on this trial design, predict the completion outcome and termination type (if applicable).
