The link implanted in my chest(outpatient procedure) has a monitor right By the bed and it monitors 24 seven. I was told sometimes you can have a fib and not be aware of it. So this monitors me. If I’m away from home I have a device I carry in my purse, looks like a small small cell phone, and it is to be held to your chest if you think you’re in a fib and it monitors you then. I have had it for a month and no signs yet. The device alerts doctors as well.
