Can a Smartphone Listen to Your Heart? A Performance Study on Detecting Abnormalities in Your Heart Sounds

Smartphone-Based Use of Phonocardiography Technique for Detection of Murmurs: Diagnostic Performance Study Protocol

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 regular clinic appointment 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.

Inclusion Criteria:

• Age: ≥22 years (adult)
• Outpatients who have undergone echocardiography within 3 years at their normal non-research follow-up clinic visit appointment

Exclusion Criterion:

• Implanted active medical devices in the torso, such as pacemakers and defibrillators
