View source: R/conversion_to_HRT.R
Scans for heart rate turbulence in a vector of RR-intervals and returns an HRTList object including all found HRT objects. The HRT criteria used were published by Schmidt et al. (more information can be found in the vignette.)

input |
(Numeric vector) RR intervals in ms |
annotations |
(Character vector) Annotations matching input |
PVCAnn |
(Character) Character that marks a VPC in the annotations |
normIL |
(Numeric) The interval length to which TS should be normalised |
normHallstrom |
(Boolean) Should the normalisation of Hallstrom be used? |
numPreRRs |
(Numeric) Number of RRs before the coupling interval that are used for filtering |
numPostRRs |
(Numeric) Number of RRs after the compensatory interval that are used for filtering |
inputName |
(String) Name of the data |
minHRT |
(Numeric) Minimal number of HRTs that are needed to create an HRTList object |
cleaning |
(Boolean) Should the input be roughly cleaned from artefacts before calculating IL and RMSSD? |
(HRTList) An HRTList object
