Paper 1:
– Polar H7 chest strap (rc=98)
– Apple Watch III (rc=96)
– the protocol of this paper should be extended according to paper:
– a motion artifact free ECG should be used
paper 2
– 95 % – 99 % agreement between a g.Nautilus ECG device and a Polar OH1
– the protocol should be adapted according to paper:
– a motion artifact free ECG should be used
Paper 3:
– inaccuracy of the AR12plus Holter monitor ECG is 94.6 %
– inaccuracy of the Polar H10 is 99.63 %
– The values of the study are not innacuracy values of Polar H10 against an ECG reference device
– they measure something completely different than in paper 1 and 2 is measured (accuracy of the ECG algorithms)
– Study 3 should be repeated according to the standard of paper 1 or 2 to get those values.
– a motion free ECG should be used
– Cardiologist Milind Desai studied in two papers a large number of devices and listed a ranking of these devices against a reference ECG device
– the protocol should be extended according to international standards
– a motion free ECG device should be used
– Rob ter Horst publishes a list of more than 50 devices on youtube, but delivers no statistical and numerical data
– Rob ter Horst uses the Polar H10 chest strap as reference device which gives an offset of 2 % compared to an ECG device. The Polar h7 chest strap has an innacuracy of 2 % against an ECG device.
– Rob ter Horst should use a motion artefact free ECG reference device
– Rob ter Horst should associate with testing groups which gives numerical and statistical values which are published
– Future tests should generally be performed according to an international standard protocol for all tests, as used in study:
-future tests should be performed generally with a motion artifact free ECG devices.
This would give a single table with an accuracy ranking of all devices which is generally accepted according to international standards.
