I had the implanted heart loop monitor. If you go by it, for knowing AF events, you really won't know until you get your report every month via your patient portal. They don't even call. Only time I got calls was once for a false sensing Pause and once when I passed out drinking the prep for a colonoscopy. I knew what to expect on the Report each month, how long & how many, from waking up in the middle of the night and seeing the high heart rate on my FitBit and my Apple Watch. Yes, I wear both for different reasons/features. And now with getting the % of Afib in the Weekly History via Apple Watch I don't even get the "morning after" Afib notifications. I just recently had mine removed, it was 35 months old and was reaching its 3 year battery life. Basically, it diagnosed my Afib in the beginning, about 3 months after implant, when my events were spaced further apart, that the 30 day Holter Monitor did not, and I went thru 2 different 30 day periods with HM's about a year apart. My episodes were quarterly or so in the beginning, then monthly with an occasional skipped month or towards the end two in a month frequency and usually 2-3 hours duration YET I still had left atrial enlargement and scarring/remodeling take place all while I thought my Afib was mild and not critical level. The HLM always showed less than 1% burden, once in a great while, the 2 in a month episodes, maybe 2%. I feel it gave me a false sense of security that my Afib wasn't "that bad" so I guess I was wrong and my EP didn't ring any alarm bells either, just signed off on the report each and every month.
