Apple Watch ECG and recorded Heart Rate data

I believe that my Apple Watch is reasonably accurate when I take an ECG reading. I have encountered a few occasions when it indicated an "inconclusive" reading, ie: an irregular heart rhythm other than Afib, such as multiple PACs or PVCs. I also have a Kardia device, which will identify PVCs and PACs when they occur. The thing about both devices is that they capture a moment in time, as opposed to a wearable heart monitor such as a Zio patch (prescription required), which keeps a sustained log of heart rhythm activity over a period of days or weeks, thereby providing more meaningful data.

You are correct in assessing the usefulness of each of the referenced heart monitoring devices. They were not meant to replace the advice of a cardiologist. That said, their usefulness has been important for some of us to offer a clue as to the direction and intensity of our Afib issues. In prior decades, most of us, including the medical establishment, were "flying blind" without these devices. My Apple watch and the Kardia most assuredly were instrumental in partnering with my Cardiology staff in arriving at treatment for my Afib, which was not only miserable, but life-threatening.
