We also (attempted to) discuss why some indices are more related than others and provided practical recommendations for choosing HRV indices more meaningfully.

I’d love to hear how you navigate the HRV index landscape and whether you think this framework could be helpful!

We clustered 89 HRV indices across:
• Two different clustering algorithms
• Two timepoints
• Two samples

and found a set of robust HRV clusters that replicate across time, methods, and samples.
