Discover the benefits of Heart Rate Analysis

In the past, Heart Rate Variability Analysis was expensive and uncomfortable. With our invention, we made it accessible to anyone

We conducted extensive research to make Heart Rate Analysis work with all types of Wearable Devices

HF - Absolute power of the high-frequency band (0.15–0.4 Hz)

LF- Absolute power of the low-frequency band (0.04–0.15 Hz)

ttlpwr (total power) - Total power is the sum of the energy in the ULF, VLF, LF, and HF bands for 24 h and the VLF, LF, and HF bands for short-term recordings

RMSSD - Root mean square of successive RR interval differences

SDNN - Standard deviation of NN intervals

SDNN - Standard deviation of NN intervals

SDRR - Standard deviation of RR intervals

SDANN - Standard deviation of the average NN intervals for each 5 min segment of a 24 h HRV recording

SDNN - index (SDNNI) ms Mean of the standard deviations of all the NN intervals for each 5 min segment of a 24 h HRV recording

pNN50 - Percentage of successive RR intervals that differ by more than 50 ms

HR Max − HR Min - bpm Average difference between the highest and lowest heart rates during each respiratory cycle

RMSSD - Root mean square of successive RR interval differences

HRV triangular index - Integral of the density of the RR interval histogram divided by its height

TINN - Baseline width of the RR interval histogram

ULF power - Absolute power of the ultra-low-frequency band (≤0.003 Hz)

VLF power - Absolute power of the very-low-frequency band (0.0033–0.04 Hz)

LF peak - Peak frequency of the low-frequency band (0.04–0.15 Hz)

LF power - Absolute power of the low-frequency band (0.04–0.15 Hz)

LF power - Relative power of the low-frequency band (0.04–0.15 Hz)

HF peak - Peak frequency of the high-frequency band (0.15–0.4 Hz)

HF power - Absolute power of the high-frequency band (0.15–0.4 Hz)

HF power - Relative power of the high-frequency band (0.15–0.4 Hz)

LF/HF - Ratio of LF-to-HF power

S - Area of the ellipse which represents total HRV

SD1 - Poincaré plot standard deviation perpendicular the line of identity

SD2 - Poincaré plot standard deviation along the line of identity

SD1/SD2 - Ratio of SD1-to-SD2

ApEn - Approximate entropy, which measures the regularity and complexity of a time series

SampEn - Sample entropy, which measures the regularity and complexity of a time series

DFA α1 - Detrended fluctuation analysis, which describes short-term fluctuations
