Summary

This study will enroll 5,000 adults across five hospitals in Taiwan to see if an artificial intelligence program can accurately detect low heart pumping function and structural heart disease using a single-lead ECG recorded from devices like an Apple Watch. Participants will have their ECG analyzed by the AI and then undergo a standard echocardiogram within 30 days to check the AI's accuracy. The goal is to validate a simple, home-based screening tool for heart failure.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Artificial intelligence software analyzing single-lead ECG recordings from Apple Watch and QOCA ECG102D devices
What this could lead to: If successful, this could provide a simple, home-based screening tool to detect heart failure early, potentially reducing the need for in-hospital tests.
What could go wrong: This is an observational study, not a treatment trial. The AI model may not be accurate enough for widespread use, and results may not apply outside Taiwan.
