Synthetic Data
Overview
By leveraging PhysioKit, we are able to generate synthetic data for a variety of physiological signals, including ECG, PPG, and respiration. In addition to the signals, the tool also provides corresponding landmark fiducials and segmentation annotations. While not a replacement for real-world data, synthetic data can be useful in conjunction with real-world data for training and testing the models.

Example
import physiokit as pk
heart_rate = 64 # BPM
sample_rate = 1000 # Hz
signal_length = 10*sample_rate # 10 seconds
# Generate NSR synthetic ECG signal
ecg, segs, fids = pk.ecg.synthesize(
signal_length=signal_length,
sample_rate=sample_rate,
heart_rate=heart_rate,
leads=1,
preset=pk.ecg.EcgPreset.NSR,
p_multiplier=1.5,
t_multiplier=1.2,
