The project, led by the University of Glasgow in partnership with AstraZeneca and NHS trusts including Greater Glasgow & Clyde and the Golden Jubilee, demonstrated the AI’s ability to interpret echocardiograms quickly and consistently during a presentation at the European Society of Cardiology conference in Amsterdam.
