The Superior Stethoscope: Eko CORE: If there is one aspect of medicine that’s more art than science, it’s the way doctors listen to heartbeats—trusting their fallible ears and memory to detect aberrations over time. Not so with Eko CORE. Once the smart adapter is attached to a stethoscope, it streams heartbeat data to the cloud so physicians can download it to a smartphone. From there, a companion app can analyze the audio and compare it to previous recordings, which may help doctors detect murmurs, heart-valve abnormalities and other conditions that “our ears are not able to,” says Dr. John Chorba, a cardiologist (and mentor to one of the inventors) who’s leading an Eko trial at the University of California, San Francisco. If the device works as planned—early signs are positive—it could not only improve overall care but also drastically reduce the need for expensive tests like echocardiograms.
