Do they know about that there are problems with expensive medical and research grade ECG devices:
and ECG motion artifacts, and are silent about it.
And do they simply take cheap reference devices as the Polar H10, which are not as accurate as medical and recearch grade ECG devices, if they would not have problems with ECG movement artefacts, and let go of highly accurate measurements? Or in other words, we know of problems with highly accurate measurement devices and methods, and let go of those?
