First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether adjusting a pacemaker's lower heart rate to an individual's optimal level can improve symptoms and quality of life in people with heart failure and bradycardia. Researchers will compare this personalized approach to the standard fixed rate of 60 beats per minute. The trial involves 106 participants and will measure symptom changes over 12 months using a heart failure questionnaire.

Active substance

Adjustment of pacemaker lower rate limit

What this could lead to

If successful, this could provide a simple, non-drug way to improve heart failure symptoms and quality of life for people who need a pacemaker.

What could go wrong

This is a small, early-stage trial (106 participants) testing a device setting change, not a new therapy. The benefit may be modest or not apply to all heart failure patients.
