Yea I've started reading up .
I need to make a few changes on health
That ECG on Apple Watch is something I really want ; but I couldn't deal with the battery capacity on the watch (we've discussed the battery before - so need to do it again ...) . I'm waiting for either Garmin to add the ECG to more devices ; or Apple to improve on the battery . I'm also checking out methods of adding auto weight in the app
hate to thro a curveball in, but you should probably get a proper monitor.
blood pressure should be read using an instrument at the same level of the heart.
a reasonably accurate device will show different pressure readings when read above or below heart level.
for example, with a watch - if you lie flat on your bed with your arm alongside you, check the reading.
then let your arm drop off the side of the bed, check that reading.
lastly, raise your arm above your head, check the reading.
you should get 3 differing pressure readings
device above heart (raised arm) will give an incorrect low reading.
device at heart level will produce the most accurate reading
device below heart (dropped arm) will give an incorrect high reading
i'm curious tho - ecg
its a diagnostic tool, unless you are able to interpret pqrst wave form values, its not much more than a gimmick on a watch.
before you shell out long dollars on any device, get your cardio's advice on what may be best for your purposes
