HRV analysis

  • Analyze specified time periods or process the whole recording using time-varying analysis
  • Parasympathetic (PNS) and sympathetic nervous system (SNS) indexes for stress and recovery monitoring
  • Time-domain HRV parameters: Mean RR, SDNN, RMSSD, pNN50, HRV triangular index, TINN, HR deceleration (DC) and acceleration capacity (AC) etc.
  • Frequency-domain HRV parameters: VLF, LF and HF band powers, peak frequencies and LF/HF ratio
