I've been reading various posts about the utility of the Apple Watch heart monitor. I wanted to offer an option for those folk who don't live in the Apple ecosystem. I live in the Samsung ecosystem and have been wearing a Galaxy 4 & now 5 watch since I was Dx and successfully treated for Afib / SVT.
The watch seems to be as accurate as Apple Watch and my cardiologist uses the ECGs I bring to him. Samsung Health app is fulsome as well.
I kept the cost down recently by buying a Amazon returned/refurbished Galaxy 5 for ~$150 instead of a latest Galaxy 6 for upwards of $400-500.
I will confess that when I'm taking ECGs out in the wilderness, I carry my Kardia device as well as it seems a bit more reliable/less finicky, but the Galaxy is really handy for general monitoring and initial assessments.
Apple has delivered a really great device, but I think Samsung's device gets overlooked the way Texas Instruments calculators swamped Casio in the graphing calculator wars.
My two cents here, but it might offer a less expensive option for some folk.
Be well.
