Official title
Development of an Algorithm to Differentiate Heart Murmurs by Timing, Disease Type, and Severity in Adult Patients Using Electronic Stethoscopes
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The Eko CORE and DUO stethoscopes are FDA-approved electronic devices that have the capacity to record heart sounds. The study seeks to expand murmur detection to include VHD classification through the development of novel ML algorithms that are able to distinguish between systolic vs. diastolic vs. continuous murmurs, as well as classify VHD type and severity, using 4-point auscultation with Eko CORE and DUO electronic stethoscopes to record heart sounds.
