We agree with Rob ter Horst. PhD:

Accuracy of Polar H10 & Holder ECG against peak detection methods

that Holder ECG devices:

https://en.wikipedia.org/wiki/Holter_monitor

are not the best choice to validate the accuracy of consumer grade heart rate monitors. But Holder ECG devices are (according to Wikipedia) suitable to monitor the heart rate of canine:

foxes, wolves, jackals, and other members of the dog family:

This proofs that Holder ECG devices still have their place in science. They can also be used to demonstate that the Polar H10 is more accurate than a Holder ECG devices:

Accuracy of Polar H10 & Holder ECG against peak detection methods

Holder ECG devices are used for canine animals, since the Polar H10 chest strap cannot be used for these animals (no, no, whe are only joking).

Nevertheless we are still convinced that a high quality ECG device is the best reference device to validate the accuracy of concumer grade heart rate monitors, and the better than a Polar H10 for this purpose.

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

Use Motion Artifact Free ECG Devices for Validation of Heart Rate Monitors

In medicine, a Holter monitor (often simply Holter) is a type of ambulatory electrocardiography device, a portable device for cardiac monitoring (the monitoring of the electrical activity of the cardiovascular system) for at least 24 hours.

Holter ECG device is not a scientifically clear defined term. This might lead to confusion. There are Holder ECG devices on the market with low-quality, but there are also other devices with a very high quality. According to this definition, also Adinstruments Equivital, g.Nautilus Pro ECG, Heartypi running on a Rasperri PI are Holter ECG devices.
