ectbcorr

PURPOSE ^

Correction of ectopic beat Presence Effect

SYNOPSIS ^

function [ht,m,r] = ECTBcorr(QRStime,ectb_times);

DESCRIPTION ^

 Correction of ectopic beat Presence Effect

 This Algorithm corrects the effect of ectopic beats, annotated
    by the function QRScorr, by calculating the corrected Heart Timing Signal,
    according to the IPFM - Modell
 With the Heart Timing Signal the HRV PSD estimation can be calculated by the 
    FHTIS - method. (see [1])
 
 INPUT:
  QRStime:      Time values of the detected QRS-Complexes
  ectb_times:   Time values of the ectopic beats generated by
                   QRScorr(output-variable: ANNOT.mov)

 OUTPUT:
  ht:           ht.data: Heart Timing Signal
                ht.time: Dedicated Time Series
  m:            Derivative of the heart timing signal,
                  dedicated time series is "ht.time"
  r:            Instantaneous Heart Rate
                  dedicated time series is "ht.time"


 Example:
   [ht,m,r] = ECTBcorr(QRStime_corr,ectb_times);
