HRV Poincare Plot VI

Owning Palette: HRV Analysis VIs

Requires: Biomedical Toolkit

Calculates the Poincaré plot of RR intervals.

Example

raw RR specifies the raw RR intervals.
error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
Poincare plot returns the Poincaré plot of the input RR intervals.
SD1 returns the standard deviation of the points perpendicular to the line of symmetry in the Poincaré plot. SD1 describes the short-time variability that is mainly caused by respiratory sinus arrhythmia (RSA).
SD2 returns the standard deviation of the points along the line of symmetry in the Poincaré plot. SD2 describes the long-time variability.
error out contains error information. This output provides standard error out functionality.
X scale returns the scale information of the x-axis of the Poincaré plot.
Minimum returns the minimum value of the X scale.
Maximum returns the maximum value of the X scale.
Increment returns the increment value of the X scale.
Minor Increment returns the minor increment value of the X scale.
Start returns the start value of the X scale.
Y scale returns the scale information of the y-axis of the Poincaré plot.
Minimum returns the minimum value of the Y scale.
Maximum returns the maximum value of the Y scale.
Increment returns the increment value of the Y scale.
Minor Increment returns the minor increment value of the Y scale.
Start returns the start value of the Y scale.
