What this trial studies

This observational study aims to assess the safety and clinical outcomes of various conduction system pacing methods, including His bundle pacing, left bundle branch area pacing, and Bachmann bundle pacing. By comparing these physiological pacing approaches to traditional right ventricular pacing, the study seeks to gather real-world data on their feasibility and effectiveness in treating conditions like AV block and atrial fibrillation. Participants will be monitored for implant success rates, procedural complications, and clinical outcomes over a minimum follow-up period of two years.

Who should consider this trial

Good fit: Ideal candidates include patients with Class I and II indications for permanent pacing, uncontrolled atrial fibrillation, or bundle branch block.

Not a fit: Patients who do not require permanent pacing or have contraindications for the pacing methods being studied may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pacing strategies that enhance heart function and patient quality of life.

How similar studies have performed: While there is limited data on the long-term performance of these physiological pacing methods, similar approaches have shown promise in improving patient outcomes in preliminary studies.
