@lioness My cardiologist office called back. I had to manually upload the data from my loop recorder monitor and send it to them. They just called back and said they didn't see anything irregular. She actually went back to last February since I had it implanted and noticed nothing to worry about. My daughter said they would have been notified as soon as I have the afib. Her husband used to have afib, but no more, so she is kind of knowledgeable on that front. I think Amazon sells the Kardia. My cardiologist knows about it and approves it. I don't use it everyday. But like my American Express card, I never leave home without it.
