I was recommended by my doctor to buy a watch that could record and take an ECG if I needed. I got the Withings ECG and here is my short review of the product.
It cost a little over £100 which feels maybe a bit expensive but it can be used to record a number of different measurements. These include steps, tracking workouts, heart rate, and an echocardiogram. The watch is used alongside an app on your phone and that was fairly easy to set up and is very intuitive. The battery was dead when I tried to use it for the first time despite a supposed 12-month life, but that may have been caused by not using it for a number of months. The battery was easy to change after finding a YouTube tutorial.
The watch itself is very simple with a basic clock face and another dial which illustrates when the ECG is in progress. It is lightweight and very comfortable to wear all day. There is only 1 button to press to start an ECG and you can take readings on the go with or without your phone nearby. It uses Bluetooth and syncs to the app each time you open it. A big issue for me is that to take an ECG requires placing your other hand over it and touching the edge of the watch for 30 seconds. This means that I need help to use it but that would normally be the case for me regardless.
You able to watch the ECG in progress, view the results as a pdf and send them to your doctor from the app once you set up an email, although this part could have been made easier. It tells you whether your sinus rythym is normal and gives your heart rate. It would be useful if you were able to download each ECG when I log in on my computer to make the process easier unless I have missed an obvious option. The watch and app can store a lot of information which is another plus point. Overall, it is a solid product and does the job as a smart ECG watch.
