Cardiac Auscultation Using Smartphones

Cardiovascular Physiological Phenomena Clinical Trial

Official title: Cardiac Auscultation Using Smartphones: a Proof-of-concept Study

Status Completed

Clinical Trial Summary

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.

Clinical Trial Description

Heart sound recording was done by researchers who were familiar with the use of the app and understand the principles of cardiac auscultation.

Reference heart sounds were recorded using an electronic stethoscope (3M™ Littmann® Electronic Stethoscope Model 3200). Study devices included Samsung Galaxy S5 (model SM-G900), Galaxy S6 (SM-G920), and LG G3 (LG-F400). ;
