Smartwatch AI could spot hidden heart condition
NCT ID NCT07291570
First seen Jun 27, 2026 · Last updated Jul 16, 2026 · Updated 2 times
Summary
This study will test whether an artificial intelligence (AI) program can accurately detect atrial fibrillation (AF) using data from consumer smartwatches. Researchers will enroll 40 adults with AF who will wear a smartwatch while their heart rhythm is also monitored with standard devices. The goal is to develop a non-invasive, continuous monitoring method that could lead to earlier diagnosis and better management of AF.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- AI algorithm using PPG-derived data from a wearable device
- What this could lead to
- If successful, this could lead to a non-invasive, continuous way to detect atrial fibrillation early using consumer smartwatches, potentially reducing strokes and hospital visits.
- What could go wrong
- This is a small, early-stage study with only 40 participants. The AI algorithm may not be accurate enough in real-world settings, and results may not apply to all types of atrial fibrillation.
