The AliveCor Kardia Band is designed to integrate with an Apple Watch. It can be purchased outside of the US. Who knows when or if the FDA will approve. Apple Inc., if they desire to do so, can push this product through the FDA faster than about anyeon.Sorry not even close, many strokes are caused by silent AFib with few symptoms. Getting FDA approval for this is difficult. Another Company, Kardia has a Apple Watch band that they have been waiting for a long time.
I use the $99 AliveCor Kardia Mobile ECG product. Its a small device you use to run a 1 channel Echo Cardiogram (a hospital uses 32 channel ECG). You press both thumbs against a metal membrane and the Kardia Mobile runs the test. My understanding (from reviews) is it will only say "see a doctor" if something abnormal is detected. I got a KArdia Mobile for $99 at Amazon -- in the USA (the FDA has approved the non watchband version of the product) It can tell if my heart has gone into A-Fib with "some confidence".
Here's the fun part.. Sure the FDA is a kill joy (we Americans are years behind the rest of the world in medical appliances). Read this carefully.. If you buy the AliveCor Kardia Mobile product in the USA you get one (and only one, guaranteed by law) review of your first ECG by a real oxygen breathing cardiologist. AliveCor doesn't want to do this but its the price to pay for selling in the USA (where the FDA wants to catch a false positive/negative on your first use.). Outside the US you don't get a cardiologist.
Think you might have a heart rhythm issue? Options..
0. Do nothing. If you are in A-Fib you could have a stroke at anytime.
1. Go to Cardiologist. A nice $800 workup (32 channel ECG with Dr. consult).
2. Buy a $99 AliveCor Kardia Mobile (USA). Register with your email, then get a free ECG analysis from a cardiologist (one only). Keep using it but trust the device to tell you if you have a heart rhythm issue (since no doctor will look at anything but the first scan.)
3. (Genius!). Pay $99 for the first scan and get reading by a Dr. Throw it away. A few months later, pay another $99 for a second device -- and get another "First scan" by a dr., Throw it away, .. . . Perpetually - just register a new email each time. You get (some of) a $800 workup for $99 at home any time you want.
