Sponsor's own description

The investigators performed a proof-of-concept study enrolling subjects with normal and pathologic heart sounds. Heart sound was recorded by auscultation on the skin of the chest wall using three smartphones: Samsung Galaxy S5 and Galaxy S6, and LG G3 . Recorded heart sounds were processed and classified by a diagnostic algorithm using convolutional neural networks.
