Summary of principal indices of blood pressure variability

Type of Index Type of BPV assessed
Frequency:

  • ‐ Spectral indices (HF, LF, VLF)

  • ‐ Residual variability

  • Short‐term BPV

  • Very short‐term BPV (spectral analysis)
Dispersion:

  • ‐ Standard deviation (SD)

  • ‐ Coefficient of variation (CV)

  • ‐ Variability independent of the mean (VIM)

  • ‐ Weighted 24h SD (wSD)a

  • Short‐term BPV

  • Mid‐term BPV

  • Long‐term BPV
Sequence:

  • ‐ Average Real Variability (ARV)

  • ‐ Interval Weighted SD (wSD)

  • ‐ Time rate of BP fluctuationsb

  • Short‐term BPV

  • Mid‐term BPV
