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.

That's a good point, I guess it's conflating 2 types of long-term: "Over-night wearing" and

"doing it every day" (where the latter would maybe be annoying with the glue-based solutions". I'll try to clarify the wording on that! - Gedankenstuecke (talk) 12:31, 1 July 2022 (UTC)

a page on this or just a note

" 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!

I'm not sure I fully understand. You mean that in some cases there's no actual PPG readings and it just uses the accelerometer-data to make a guess for the heart rate? Do you have an example of that? I know that most wearables that use PPG take movement into account but rather in order to remove the noise/artifacts that are introduced in the readings as a result of moving the arm. In that case I wouldn't say it's 'guessing'? - Gedankenstuecke (talk) 12:31, 1 July 2022 (UTC)

yes and yes All those bands which do not register any heart rate increase if the one hand they were on was held still. I have run into at least 3 ex miband 3. If you want one like then just search for cheap smartwatches on amazon. I suppose the expensive new wearables do the "help ppg out with accelerometry" thing and that is not at all what I am talking about.

Ah, got it. So basically some cheap devices basically don't do PPG at all but rather make up the numbers just based on how much movement the accelerometer registers. - Gedankenstuecke (talk) 07:31, 6 July 2022 (UTC)

Should this be a topic page?

I noticed that these types of pages (those that contain collections of tools on a certain topic) are sometimes in the "tools" and sometimes in the "topics" category. The topic page that this page has as a property in the tool infobox redirects back to this page. I'd suggest changing it to a topic page, also as there is no other topic page on heart rate yet (only HRV). Title suggestion: "Heart rate and pulse tracking". What do you think?
