Medical devices to monitor heart rhythm (i.e., Alivecor, KardiaMobile)

@ninski, the Apple iWatch Series 9 starts at $399 if it's not on sale somewhere.

You can get cheaper, but effective, devices that do the same thing. A Kardia mobile is much less than a Galaxy or an Apple, or a Garmin, smart watch. The better Fitbit devices also record heart rates and rhythms AFAIK, without checking on the www to verify. You can also get old new-in-box watches that, once you get them and register them, you update the firmware and they'll then have the capabilities of the more up-to-date watches. For exampl, Galaxy is about to launch their Galaxy 7 series, but my Galaxy 4 was updated about 20 months ago and could then read and produce an ECG. You might be able to find older products for about half their original prices, which have only gone up over time.

Thank you! I’ll have to start saving up!

I use the Kardia and otherwise use the patch monitor prescribed by my doctor. It is helpful to read about watches for a period like now, which is following an afib episode and often involves palpitations while my heart recovers.
