Study Summary

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.

Primary Outcome

Develop a model that can classify murmurs based on the timing of the murmur in the cardiac cycle, allowing the algorithm to distinguish between systolic, diastolic, and continuous murmurs using time-synchronized ECG and PCG data.
