Can Smartphones Listen to Your Heart? A Performance Study on Detecting Inborn Heart Diseases in Your Heart Sounds

Enrolling by invitation

Conditions studied: Congenital Heart Disease (CHD)

In brief

This observational study aims to assess the performance of the software called ausculto™. ausculto™ is a collection of computer algorithms that intend to analyse heart sounds recorded from the built-in microphone of a smartphone for abnormal sounds. Participants will have their heart sounds recorded during their normal attendance at the hospitals after consenting to participate in this study. Researchers will manually annotate the recorded heart sounds to create a database for use in future training and testing of artificial intelligence (AI) intended for medical uses.
