Abstract:
Methods, apparatuses, and systems for quantifying fatigue of a subject are disclosed. The methods may include measuring an electrocardiogram (ECG) signal from the subject. The methods may further include calculating, with a processing device, a Heart Rate Variability (HRV) metric in response to the ECG signal. The methods may additionally include calculating, with a processing device, a fatigue level in response to the HRV metrics.
