Where to pace? new study maps best heart spots for pacemakers
NCT ID NCT07603648
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how different places in the upper heart (atrium) affect the heart's electrical signals when a pacemaker is being put in. About 35 adults who need a pacemaker will have short tests at several pacing spots during their procedure. The goal is to find which spot gives the best electrical pattern, which may help doctors choose better pacing locations in the future.
