AI heart reader aims to spot deadly rhythms before It's too late
NCT ID NCT05890716
First seen Jun 25, 2026 · Last updated Jul 21, 2026 · Updated 3 times
Summary
This study is testing a cloud-based artificial intelligence platform called Willem that analyzes ECG recordings to detect heart rhythm problems and abnormal patterns. Researchers will compare the AI's readings to those of board-certified cardiologists in over 5,300 high-risk cardiac patients. The goal is to see if the AI can match or exceed human expert accuracy, potentially leading to earlier detection and prevention of serious events like sudden cardiac arrest.

- Active substance
- AI-powered ECG analysis software
- What this could lead to
- If successful, this AI could help doctors catch dangerous heart rhythms faster and more accurately, potentially preventing heart attacks or sudden cardiac death.
- What could go wrong
- This is an observational study, not a treatment trial. The AI may not perform as well in real-world settings or on all types of heart patients.
