090f. Which devices are used to measure heart rate in scientific studies?

  • A key scientific paper in this context is this one:

Lin LI. A concordance correlation coefficient to evaluate reproducibility.

Biometrics 1989

;45:255-68. 10.2307/2532051

This paper has been cited 8580 times to this date:

  • Why has this paper been so often cited?
  • It is a key paper which say something about reproducability.
  • These requirements listed in the paper are:
  • A three lead (or 3 channel) ECG device.
  • The Mason-Likar electrode placement.
  • ECG-based HR has to be determined by visual assessment of a trained research personnel.
  • Only view PPG devices are offered by manufacturers of devices for scientific studies.
  • They mainly offer ECG devices with 3 ECG channels or more which fullfill the above requirements.
  • And neither Rob ter Horst’s 100 smartwatches, nor the heart rate monitors tested in the papers listed in this review:
090. Review of Accuracy Studies of Consumer Grade Heart Rate Monitors: Methods, Testing Protocols, Reference Devices
  • fullfill the requirements.
  • And only view scientists use heart rate monitors which are not 3 lead (or more) ECG devices for scientific studies.
