especially for accuracy validatiors as Rob ter Horst who is a postdoctoral researcher in research center for molecular medicine basic medical research
even though Rob does not want to change to ECG validation, we think that it is a failure to keep the topic secret and not to recognize the value of ECG accuracy validations studies, especially if Apple watches are also used for clinical applications
The Polar H10 chest strap might be the most accurate device for sporting activities with strong body movements,but for clinical and research applications and for sporting activities on a treadmill below 15 km/h, 3 lead ECG devices are gold standard for HR measurements which means the most accurate devices.
There is a reason these clinical and research grade devices are very expensive, and to ignore studies done with these devices is a failure
