Pacemaker placement showdown: which spot protects the heart best?
NCT ID NCT07360067
First seen Jun 25, 2026 · Last updated Jul 29, 2026 · Updated 3 times
Summary
This study looks at 200 adults with sick sinus syndrome who need a pacemaker. Researchers will compare two places to put the pacing wire—Bachmann's bundle or the right atrial appendage—to see which one better prevents heart damage. The goal is to learn which site leads to healthier heart structure and function over time.

- If successful, this could guide doctors to choose a better pacing site to reduce heart damage in patients with sick sinus syndrome.
- What could go wrong
- This is an observational study, not a treatment trial, so it won't directly improve health. Results may not apply to all patients.
