The detection range for heart rate is 30 – 220 bpm (beats per minute). Based on both internal and external validation studies, Hexoskin’s heart rate measurements show no significant differences when compared to standard laboratory ECG monitors. A validation study by [Villar *et al.* (2015)](https://www.hexoskin.com/pages/scientific-publications) demonstrated that there were no significant differences between heart rate measured by Hexoskin and by a laboratory ECG (ECG module, Finometer, Finapres Medical Systems, Arnhem, the Netherlands, sampled at 1 kHz) during lying, sitting, standing, and walking conditions. Heart rate readings showed low variability, minimal error, and strong consistency between the two methods. Bland‑Altman plot analyses revealed only very small deviations of the mean value from zero across all conditions, with 95% limits of agreement of ‑3.2 and +2.9 bpm. - [Hexoskin OneSync Software](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#main-content) - [Hexoskin OneSync Advanced Features](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#hexoskin-onesync-advanced-features) - [Hexoskin OneSync Basics](https://support.hexoskin.com/hexoskin-onesync-software?hsLang=en#hexoskin-onesync-basics) - [Hexoskin Data Analysis](https://support.hexoskin.com/hexoskin-data-analysis?hsLang=en) - [Hexoskin Support Topics](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#main-content) - [Hexoskin Mobile App](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-mobile-app) - [Hexoskin Articles](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-articles) - [Hexoskin Set-up and Configuration](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-set-up-and-configuration) - [Hexoskin Recorder](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-recorder) - [Hexoskin Troubleshooting](https://support.hexoskin.com/hexoskin-support-topics?hsLang=en#hexoskin-troubleshooting) - [Hexoskin FAQ](https://support.hexoskin.com/hexoskin-faq?hsLang=en#main-content) - [Frequently Asked Question for the Hexoskin community](https://support.hexoskin.com/hexoskin-faq?hsLang=en#frequently-asked-question-for-the-hexoskin-community) - [Order](https://support.hexoskin.com/hexoskin-faq?hsLang=en#order) - [Hexoskin OneView dashboard](https://support.hexoskin.com/hexoskin-oneview-dashboard?hsLang=en) - [Hexoskin OneSync](https://support.hexoskin.com/hexoskin-onesync?hsLang=en) - [Hexoskin Smart Garments](https://support.hexoskin.com/hexoskin-smart-garments?hsLang=en#main-content) - [Hexoskin Device](https://support.hexoskin.com/hexoskin-smart-garments?hsLang=en#hexoskin-device) - [Hexoskin App](https://support.hexoskin.com/hexoskin-app?hsLang=en) - [Hexoskin Dashboard](https://support.hexoskin.com/hexoskin-dashboard?hsLang=en) - [Help for Developers](https://support.hexoskin.com/help-for-developers?hsLang=en) - [Ordering Your Hexoskin](https://support.hexoskin.com/ordering-your-hexoskin?hsLang=en) - [Hexoskin Support](https://support.hexoskin.com/hexoskin-support?hsLang=en) [![Hexoskin - Logo - No Tagline - Rectangle - White - Transparent-Nov-28-2023-04-38-48-1716-PM](https://support.hexoskin.com/hs-fs/hubfs/Hexoskin%20-%20Logo%20-%20No%20Tagline%20-%20Rectangle%20-%20White%20-%20Transparent-Nov-28-2023-04-38-48-1716-PM.png?width=200&height=50&name=Hexoskin%20-%20Logo%20-%20No%20Tagline%20-%20Rectangle%20-%20White%20-%20Transparent-Nov-28-2023-04-38-48-1716-PM.png "Hexoskin - Logo - No Tagline - Rectangle - White - Transparent-Nov-28-2023-04-38-48-1716-PM")](https://hexoskin.com) 5800, Saint-Denis, Suite 601, Montréal (Québec), Canada Copyright © 2026, Hexoskin
