My father is a cardiologist.

Taken from LinkedIn: -- My father is a cardiologist. I sent him this screenshot last week without telling him where it came from. He called me within an hour. Worried. Asking where I got the test, when, and for what reason. I told him: it came from the SOND Dreambuds. While I was sleeping. He went quiet for a second. Then: "You mean you can record an SCG uninterrupted for a full night? Just from earbuds?" Yes. For people outside of cardiology, SCG (seismocardiography) captures the actual mechanical vibrations of your heart beating inside your chest. It's typically recorded with sensors strapped to your sternum. In a lab. For a few minutes at a time. We're doing it from inside the ear canal. For 8 hours. While you sleep on your side. That's what we built at SOND. For us, it's the engine behind real-time sleep intervention. SCG gives us cardiac timing precision that PPG (the green light on your wrist) simply cannot reach. For my father, a lifelong cardiologist, it was the first time a consumer device made him stop and rethink what's now possible. "Think of all the applications" was the next thing he said. - We're launching on Kickstarter soon - you'll be first in line. * 700 people reacted to this story on LinkedIn: * Learn more or pre-order here
