HRV Statistics VI

Owning Palette: HRV Analysis VIs

Requires: Biomedical Toolkit

Calculates the statistic information of RR intervals.

Example

	raw RR specifies the raw RR intervals.
	detrend? specifies whether to detrend raw RR. The default is FALSE. If detrend? is TRUE, this VI calculates NN50, pNN50, RMSSD, and RR std by using the detrended RR intervals.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	statistics measurements returns the statistics information of the input raw RR intervals. NN50 returns the number of pairs of adjacent RR intervals with a difference of more than 50 ms. pNN50 returns the percentage of NN50 in all RR intervals. RMSSD returns the RMS of the differences between adjacent RR intervals, in milliseconds. HR std returns the standard deviation of heart rate, in beats per minute. HR mean returns the mean heart rate, in beats per minute. RR std returns the standard deviation of RR intervals, in seconds. RR mean returns the mean RR interval, in seconds.
	error out contains error information. This output provides standard error out functionality.
