PlotBaroreflexAnalysis

Visualization of the data computed by the Baroreflex_Analysis functions.

Calling Sequence

PlotBaroreflexAnalysis(result ,Title,selection)

Parameters

result
The result data structure returned by the Baroreflex_Analysis function.
Title
a character string that will be used to set the title of the graph.
selection
a vector of character string with possible values: "raw","filt","energy","dsp","freq","disp" which indicates the optional signals properties to be plotted.
  • "raw" stands for initial RR and SBP signals.
  • "filt" stands for band pass filtered input signals.
  • "energy" stands filtered signals windowed energy.
  • "dsp" stands filtered signals power spectral density.
  • "freq" stands filtered signals instantaneous frequencies.
  • "disp" stands filtered signals instantaneous frequencies dispersion.
The default value is ["raw","energy","freq"]

Description

PlotBaroreflexAnalysis plots the data computed by the Baroreflex_Analysis function.

The Tools/Scroll on menu asks for the time window length and then enable scrolling using right and left directional arrow keys. Use Tools/Scroll Off menu to go back to the full display.

Examples

d=read(cardiovascularpath()+"demos/DATA/tilt_divers",-1,5)';//[RR SBP DBP Vt time] 
freq_sampling=2;
shift=600;
RR= d(1,shift:$);
SBP=d(2,shift:$);
