Hey there,

we are interested in investigating in HRV and stress / breathing / relaxation / recovery etc.

We would like to use a device / software which allows real-time online feedback of a HR-curve to give participants direct feedback on the effect of breathing on their heart rate. Additionally the system should include HRV analysis (different indices like RMSSD etc.).

Most software needs to get feed with existend data.

Thank you in advance and many greetings

Johannes
