Comparison and results of the three different methods to differentiate between AF and SR based on the recorded pulse wave signals, using different statistical approaches and combinations thereof.

nRMSSD, normalized root mean square of successive difference of RR intervals; ShE, Shannon entropy; SD1 and SD2 derived from Poincaré plots.
