- Willing and able to provide informed consent
Exclusion Criteria:
- Persistent atrial fibrillation (AF) (>7 days), long-standing persistent AF, permanent AF, or prior atrioventricular node ablation
- Prior cardiac implantable electronic device (CIED) requiring replacement, upgrade, or revision
- Indication for cardioverter-defibrillator (ICD) or cardiac resynchronization therapy (CRT-D)
- Prior cardiac surgery, severe hepatic or renal dysfunction, or other life-threatening systemic diseases
- Acute myocardial infarction within 3 months before enrollment
- Persistent left superior vena cava or dextrocardia
- Pregnant or breastfeeding women, or women of childbearing potential not using effective contraception
- Participation in another clinical trial that may interfere
- Any condition that, in the opinion of the investigator, makes participation unsuitable

Intervention / BehandlingIntervention / Behandling |
|---|---|
|
Eksperimentel: PSB pacing
Patients were randomly assigned to receive posterosuperior bundle pacing for atrial pacing during regular pacemaker implantation procedures.
|
Atrial pacing lead implanted at the posterosuperior bundle region.
Left bundle branch area pacing will be applied if ventricular pacing is necessary.
|
|
Aktiv komparator: RAA pacing
Patients were randomly assigned to receive right atrial appendage pacing for atrial pacing during regular pacemaker implantation procedures.
|
Atrial pacing lead implanted at the right atrial appendage.
Left bundle branch area pacing will be applied if ventricular pacing is necessary.
