Pacemaker tweak may also lower blood pressure
NCT ID NCT04463121
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether special pacing signals from a pacemaker can improve heart function and lower blood pressure in people who need a pacemaker and also have high blood pressure. Researchers will measure heart pressure and volume using a thin catheter inside the heart. The goal is to see if these signals can help control blood pressure while treating a slow heart rate.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Cardiac Neuromodulation Therapy (CNT) pacing signals delivered via a pacemaker device
- What this could lead to
- If successful, this could help develop a pacemaker-based treatment that lowers blood pressure while managing slow heart rate.
- What could go wrong
- This is a small, short-term study done just before a pacemaker implant, so results may not apply to long-term use or to broader patient groups.
