The accuracy value of 99.6 % of the Polar H10 is not the accuracy value against a motion artifact free ECG device

Last Updated on July 7, 2022 by pg@petergamma.org

The mentioned study says only something about the accuracy of the algorithms of the Polar H10, and says nothing about the accuracy of the Polar H10 against a high quality motion artifact free ECG device.

The Polar H10 was not tested against a high quality motion artifact free ECG device:

in the study mentioned above.

Two other studies use high quality ECG devices as reference device:

One study says, that a Polar H7 chest strap is the closest to an ECG device used in clinical research, followed by an Apple watch:

A second study using a g.Nautilus references devices says, that the Polar OH1 can be used instead of an ECG device as far as accuracy is concerned:
