RHRT (version 1.0.1)

vectorToHRT: Convert a vector to HRTList

Description

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.)

Usage

vectorToHRT(
  input,
  annotations = NULL,
  PVCAnn = "V",
  normIL = c_normIL,
  normHallstrom = TRUE,
  numPreRRs = c_numPreRRs,
  numPostRRs = c_numPostRRs,
  inputName = as.character(NA),
  minHRT = 5,
  cleaning = TRUE
)

Arguments

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?

Value

(HRTList) An HRTList object

Examples

# NOT RUN {
# You can use annotations to give the VPC indices
# Without annotation data RHRT will find VPCs based on common filtering criteria
vectorToHRT(testdataLong, annotations = testdataLong_Ann, PVCAnn = "V")

# Find HRTs with a broader range of sinus beats before and after the VPCs
vectorToHRT(testdataLong, inputName = "Dummy Measurement", numPreRRs = 10, numPostRRs = 20)
 
# Adjust the normalisation parameters
vectorToHRT(testdataLong, testdataLong_Ann, normHallstrom = FALSE, normIL = 900)

# }
