You correctly note that higher HRV values are generally better, but don’t explain this interpretation in terms of sympathetic tone and actual heart rate. You passively note that HRV is typically lower during exercise, obviously because the heart rate is increased and is likely at a relatively fixed level with sustained effort.

Thanks to Jayadev for his great support.

I also have no need to use heart monitor contact gel or anti static spray.
Thanks to the team.![Profile Photo]()

When measured continuously, most individuals have HRV values between 0 – 100, where higher values are better. It is normal for HRV to vary during the day depending on the time of measurement. When continuously monitoring HRV, it…Read More
