90.02 Research & medical grade ECG devices which some of those were used to study the accuracy of consumer grade HRMs in different papers

Question of the Meditation Research Insitute Switzerland (MRIS) to the g.tec medical support:

«It is published by g.tec medical that the NAUTILUS PRO FLEXIBLE can record artifact-free EEG signals from the headset.

In the following paper in PLOS ONE:

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0217288

the authors use a Nautilus device. Do Nautilus devices also offer to record motion artifact free ECG signals?

Answer of the g.tec medical support:

«Unfortunately, we know of no manufacturer who can manage that.

We can minimize them. In our particular case, we can use active electrodes. But that system is then very expensive, and for large or intense movements you will still have some artifacts, or baseline fluctuation.

You can also chose to place electrodes on thorax, rather on limbs. That would further minimize artefacts.»
