What this trial studies

This clinical trial evaluates a novel setup algorithm for cardiac neuromodulation therapy using the Moderato® Implantable Pulse Generator in patients requiring dual chamber pacemakers. Participants will undergo two setup sessions to test different pacing algorithms after a run-in phase of standard pacing. The study aims to assess the effectiveness of these algorithms in managing hypertension and bradycardia through 24-hour ambulatory blood pressure monitoring. Follow-up visits will occur at 3, 6, and 12 months to evaluate long-term outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who require a dual chamber pacemaker and have stable hypertension.

Not a fit: Patients with secondary causes of hypertension or those not requiring pacemaker implantation may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could improve blood pressure management and overall cardiac function in patients with hypertension and bradycardia.

How similar studies have performed: Previous studies have shown promise with similar pacing approaches, indicating potential for success in this novel application.
