NCT ID NCT07256678
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This observational registry will follow over 6,000 people who have been prescribed the Jewel P-WCD, a wearable defibrillator that can detect and treat dangerous heart rhythms. The goal is to confirm the device continues to work safely and effectively in everyday life. No new treatments are being tested; instead, researchers will collect data from routine commercial use.
