A paper of the Swiss Federal institute of Magglingen says:
https://pubmed.ncbi.nlm.nih.gov/31004219/
«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».
But there is no scientific proof that the Polar H10 is the gold standard for these activities. In the paper the Schiller Medilog AR12 Plus Holter Recorder was tested against the Polar H10 chest strap. But the Schiller Medilog cannot handle with noisy ECG signals. Other ECG devices can, as for instance:
1. The iWorx TA 220 with the iWorx ECG toolbox
2. HeartPy with for instance an OpenBCI Cyton board can handle with very noisy ECG signals
3. The Adinstruments Equivital with the Labchart software offers noise and motion artifact free ECG
4. ECG devices from g.tec medical can minimize ECG motion artifacts by using active electrodes
But these four devices where not tested in the paper mentioned above and compared to the Polar H10 chest strap. Why where these not tested in the paper which was funded partly by Polar? Rob ter Horst tested the accuracy of 100 smartwatches, but not the four devices mentioned above. Why did Rob not test those?
