I guess this could have gone under tech, but it is really a health thing, so I am posting it here. When the new Series 4 Apple Watch came out, it had the capability to take an EKG, but the app for it was only just released today, along with the new iOS updates. Naturally, I had to try it out, and my first results came out with a normal sinus rhythm. It will be interesting for me to be able to see what it shows on the days when my heart is all out of sync and beating 150 bpm. Here is what it looks like from the iphone app (it saves all of my readings, and then can also be sent to my doctor), and also a quick video that shows how this works.
