Talk:Heart rate tracking

" As such they might be less appropriate for long-term data collection, similar to chest straps." The glue on ecg are a hassle but they are also designed to be worn for at least a day .All those formal medical devices like the Zeo zio? are "stick it on for a week" glue ecg probes. Chest straps are designed to be worn for the length of an exercise period like two hours. Chest straps are also worse to wear to sleep. How long is long term? Certainly not like chest straps.

" I DG (talk) suspect it may be accelerometry - activity based guessing in the bad ones. This is very bad because the difference between what accelerometry would predict and what is actually happening is very important information."

In other words the difference between what the heart rate user is experiencing under exercise and what they should be is very important information and the device pawns off the first as the second. The difference should be pretty obvious if user does exercise that does not involve moving the relevant arm. Lot of devices do this with other sensors and then defend their dishonesty with words. They should not be allowed and there should be a page all about it!
