Create Simulated ECG PhysioExperiment

Generates a PhysioExperiment object containing synthetic ECG data with Gaussian-shaped R-peaks at regular intervals. The resulting object is suitable for testing R-peak detection, RR interval computation, and HRV analysis pipelines.

Usage

make_ecg(n_time = 5000, n_channels = 1, sr = 500, heart_rate = 72)

Arguments

n_time

Number of time points (default: 5000).

n_channels

Number of ECG channels (default: 1).

sr

Sampling rate in Hz (default: 500).

heart_rate

Heart rate in beats per minute (default: 72).

Value

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