He told me it was a lot less expensive than the Zio patch or Holter monitor and good enough to use to see if my SVT gets worse. When I had to wear those devices for 3 weeks (first the Holter monitor, then they switched to the Zio patch because it was more discreet) it was like, $1,500 I had to pay. The watch was only $300 and I can show him at my appointments. The watch could not diagnose me, and I have no idea what I’m looking for, but it seems to be worth it.
