Chesterfield, I've had a Medtronics LINQ inserted heart monitor for 2 years. They told me 3 year battery life on this one. Done under local, no soreness or other problems. After the first couple of months I've completely forgotten about it. I lean heavy boxes against it while carrying, etc. When I'm bored I can feel to make sure it's still there. It's about 2" long thin rectangle. I can put my fingers on both of the long sides to "pinch/squeeze" it between my fingers, but it doesn't give any sort of feeling or pain, just weird.
It does not trigger at the airport, which was a big concern as a 150 segment per year flyer pre-covid. I still walk through TSA just fine, although I do carry a card in my wallet to explain what it is, just in case.
As a scientist and overall data geek, it's disappointing because the signal goes to the Doc and they ain't sharing. Pretty sure they don't want someone that is good with Excel or Minitab getting ahold of the data :-) Same deal, we'll call you if we see something we don't like, and knock on Bondo I haven't received a call. Just the insurance notice of the monthly monitoring fee, just like the alarm company......
There is a bedside device to download each night. The most humorous part was at insertion, when they had to take the very-mouse looking thing and set it on my chest to pair with the monitor. Two beeps and a green light and we were connected.
I have the option to have it removed when the battery dies, and it's a quicker procedure than the insertion. I don't plan to do that - it's so unobtrusive that it's not worth the time to go have it removed. They can get it next time they're in there for something else. Kind of like "while I'm in there" mentality with engine or suspension work.
DM me if you want to talk on the phone
Bluetooth/Wifi is the wave of the future in medical. There is a ton of work in medical wearables, with glucose monitoring being the most common now. In the future, expect to get a care pack from your doctor to wear some sensors for a week and then have a tele-call and not even need to go into an office. Your body will just transmit all of the data, real-time.
