| 1 | Garmin | Venu | 2 | according to the data of Rob, one of the most accurate Garmin watches | improved optical HR monitor | Polar H10 (1*) | not discussed in this table | Rob ter Horst | ||
| 2 | Garmin | Venu | 2 Plus | not as accurate as Venu 2 | Polar H10 (1*) | not discussed in this table | Rob ter Horst | |||
| 3 | Garmin | Venu | SQ | After firmware update | eventually better accuracy than Venu SQ before the update | Polar H10 (1*) | not discussed in this table | Rob ter Horst | ||
| 4 | Garmin | Venu | SQ | Before firmware update | inaccurate | Polar H10 (1*) | not discussed in this table | Rob ter Horst | ||
| 5 | Garmin | Venu | no data from Rob ter Horst | Polar H10 (1*) | not discussed in this table | Rob ter Horst | ||||

(*1) The Polar H10 single-lead ECG chest strap is gold standard for RR interval assessments for intense activities with strong body movements [90.10.1].
(*2 ) 3 lead ECG devices are gold standard for HR measurement for activities in which ECG noise and motion artifacts do not play a role, for instance for runs on a treadmill at 4, 5, 6, 7, 8, and 9 mph at zero inclined [90.8.5].

Remark: The Garmin Venu SQ was used in the following conference paper about breathing rate estimation:
- Firmware updates of Garmin watches eventually affect the heart rate accuracy, which can change the parameters of the Garmin Venu SQ which was used in this paper.
