FAQ

Questions HRV Coherence Calculator owners ask.

  • 01

    What is the difference between RMSSD and SDNN?

    RMSSD measures short-term variation (parasympathetic activity), while SDNN assesses total variability. Both metrics are calculated using dedicated capabilities: calculate_rmssd for the former and calculate_sdnn for the latter.

  • 02

    Do I need to provide age and sex?

    Yes. The classification of your coherence level requires demographic context. The classify_coherence_level capability uses your age and sex to compare calculated metrics against established physiological norms.

  • 03

    What are the minimum requirements for input data?

    Data constraints vary by metric. calculate_rmssd requires a minimum of 3 readings, and calculate_sdnn requires at least 5 readings to ensure statistical reliability.
