Create Simulated ECG with Irregular R-R Intervals

Generates a PhysioExperiment object containing synthetic ECG data with irregular beat timing. Every 5th beat is premature (60\ interval), followed by a compensatory pause (140\ Useful for testing ectopic beat detection and RR interval correction.

Usage

make_ecg_irregular(n_time = 5000, sr = 500, heart_rate = 72)

Arguments

n_time

Number of time points (default: 5000).

sr

Sampling rate in Hz (default: 500).

heart_rate

Base heart rate in beats per minute (default: 72).

Value

A PhysioExperiment object with a single "raw" assay containing the simulated ECG signal with irregular beats.
