@isabelk I also use the Kardia. It shows fib and heart rate, as well as supraventricular ectopy, PVC's. You link it to your phone's Bluetooth using an app on the phone. The Kardia is as long as a credit card and narrower. You put two fingers on either side and watch for 30 seconds. You can also use more leads, which involves placing it on a bare knee.

The Kardia is not continuous. It runs for 30 seconds when you choose to use it. You can use it over and over again. But it is not a device to detect asymptomatic afib over periods of time. For that I get a patch monitor from my doctor (in my case, no hidden afib, I always feel it, so Kardia works for me).
