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);
