Automatic HRV analysis

Hexoskin automatically calculates HRV values during a rest or sleep activity only.

 

In fact, based on the literature, HRV values can only be accurately and meaningfully measured during a period with very minimal activity and movement. Movement can cause outliers in the ECG signal and then bias the HRV calculation and interpretation.

 

During a Rest activity or by performing a 5 Minutes Rest Test (in the Fitness Tests section of the Hexoskin App), Hexoskin will automatically provide you with an RMSSD value on the app and also on the dashboard after syncing the data. 

 

After tagging a Sleep activity, the Hexoskin algorythms calculate the following HRV values:

• HRV(HF)
• HRV HF Norm Min
• HRV HF Norm Max
• HRV LF Norm Avg
• HRV LF Avg
• HRV HF Avg

 

These HRV parameters are provided in the data export from the dashboard (after syncing data).
