„A simple chest strap such as the Polar H10 might be recommended as the gold standard for RR interval assessments if intense activities with strong body movements are investigated.“

For all other physiologists which are NOT interested in intense activities with strong body movements, 3 channel ECG devices are gold standard for heart rate measurements. as Peter Gamma from www.petergamma.org has discussed intensively:

Is it because of the intensive reviewing of Peter Gamma from www.petergamma.org

that Thomas Wyss has now his Polar H10 chest strap data in the balena cloud?

But can a sports physiologist like him handle with his Polar H10 chest strap data there?

And the non-sport physiologists like Peter have to go here:

To build their own multi-physiological device based on InfluxDB.
