Arguments

data: A dplyr::tibble with a 'time' column (RR intervals). Assumes the first 3 minutes are lying and the next 3 minutes are standing.
secondary_threshold_percent_lying: Numeric, percentage change threshold for secondary filtering during the lying phase (default: 20).
secondary_threshold_percent_standing: Numeric, percentage change threshold for secondary filtering during the standing phase (default: 20).
transition_exclusion_time: Numeric, duration (in seconds) to exclude around the transition (default: 45). Increased default.
initial_stabilization_time: Numeric, duration (in seconds) to exclude at the beginning of the lying phase (default: 60).
min_segment_length: Numeric, minimum segment length in seconds (default: 30).
min_segment_beats: Integer, minimum number of beats in a segment (default: 30)
...: other parameters passed to detect_hrv_artefacts

Value

A list containing:

rmssd_lying: RMSSD for the lying phase (or NA).
rmssd_standing: RMSSD for the standing phase (or NA).
rmssd_values: A numeric vector of all segment RMSSD values.
segment_lengths: A numeric vector of segment lengths.
segment_beat_counts: An integer vector of segment beat counts.
aggregated_rmssd: Aggregated RMSSD (mean of a ll segments).
n_segments: Number of segments
