Read the article. The device mentioned here has to be held over the heart to measure blood pressure. It doesn't actually work while on the wrist, apparently.
The device mentioned here has to be held over the heart to measure blood pressure.
Elevating the device to to the level of your heart seems like standard practice. Every home blood pressure monitor I've ever used requires this. And it's also the way my doctor does it in his office with both electronic and the squeezie bulb blood pressure thing.
it works on the wrist, it only takes the reading when you put your wrist (and the watch) over your heart. It actually forces you to literally put your wrist at heart level.
As such, this is pretty lame.
