-*Extra beats* are corrected by removing the extra R-
-wave detection corresponding to the detected short
-RR interval and RR interval series is then recalculated.
-
-*Missed beats* are corrected by adding new R-wave
-occurrence time so that it divides the detected long
-RR interval into two equal halves and RR interval series
-is then recalculated.
-
-*Long or short beats*, are corrected by interpolating
-new values to the RR time series.
-
-*Ectopic beats* are corrected by replacing corrupted
-RR times by interpolated RR values.
