If you’ve ever had the misfortune of needing continuous EKG monitoring, you’ve probably used a Holter monitor. It’s like carrying a 1980s walkman made of metal with a bunch of wires going from it to your chest. If that sounds uncomfortable, and as if you won’t sleep or enjoy showers much for the two weeks you need to carry it around, you’ve neatly stumbled across the use case for the Mawi Heart Patch. The company just released its product, a two-lead cardiac monitor that can be read in real time.

There are consumer-grade products that can do EKG readings, including the Withings ScanWatch (and its fancier-looking sibling, the ScanWatch Horizon), and there are other patches on the market, such as the Zio patch, but Mawi claims to have done something unique, and suggests that its Heart Patch is the first ever single-use, two-lead cardiac monitor to reach the market.
