- (double) fHFxHF

Calculation of fHF * HF, use this rather than fHFhf which is more of an internal placeholder.

Property Documentation

- (double) breathPeak [read, write, assign]

The frequency in Hz within the region .15 - 1.5Hz containing the highest spectral power. This corresponds roughly to the breathing frequency.

- (double) fHF [read, write, assign]

The frequency in Hz within the HF region containing the highest spectral power.

- (double) fHFhf [read, write, assign]

fHF * HF

- (double) hf [read, write, assign]

The sum of the high frequency spectral components from .15 - .4 Hz in units of ms^2

- (double) lf [read, write, assign]

The sum of the low frequency spectral components from .04 - .15 Hz in units of ms^2

- (double) pNN50 [read, write, assign]

The percentage of successive intervals that differ by more than 50 ms

- (OrderedDictionary *) psd [read, write, retain]

Power spectral density results in units of s^2 for each frequency bin from 0 - 2Hz

- (double) rmssd [read, write, assign]

The root mean squared of successive deviations of the time series signal.

- (double) stdev [read, write, assign]

The standard deviation of the time series signal.

- (double) time [read, write, assign]

The time in seconds for which this result was calculated. Since the time series data is windowed, time is estimated at the center of each window.
