Extract F wave features from ECG

Source: R/fwave.R
extract_f_waves.Rd

This function analyzes F waves in an ECG signal, extracting various characteristics.

Usage

extract_f_waves(
  object,
  lead = NULL,
  qrs_method = "adaptive_svd",
  f_characteristics = "amplitude",
  ...
)

Arguments

object

An object of class egm

lead

Optional. A character string specifying the lead to analyze. If NULL (default), all available leads will be processed.

qrs_method

Method for ventricular signal removal. Default is "adaptive_svd" for adaptive singular value decomposition.

f_characteristics

Vector of characteristics to analyze from ECG signal. Options: "amplitude", "irregularity", "dominant_frequency"

...

Additional arguments passed to methods

Value

A list containing F wave features for each processed lead
