Smart vest could help doctors place pacemaker leads more accurately
NCT ID NCT06509763
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a special vest that creates detailed maps of the heart's electrical activity without any needles or surgery. Researchers used it during pacemaker lead implantation in 50 patients to see if it could confirm when the lead was in the right spot. The goal was to validate existing ECG criteria for left bundle branch pacing, which may help improve outcomes for people needing cardiac resynchronization therapy.

Active substance
ECGI system (non-invasive mapping vest)
What this could lead to
If successful, this could improve how doctors confirm correct lead placement during pacemaker implants, potentially making the procedure more reliable.
What could go wrong
This is a small, completed validation study, not a treatment trial. The findings may not change practice without larger confirmatory studies.
