Early diagnosis is a critical prognostic factor, but this can be clinically challenging. Heart rate variability (HRV), the beat\u2010by\u2010beat variance in heart rate (HR), may provide a unique assessment for the presence of AN because it has clinical utility as a biomarker of cardiac autonomic control in various populations (e.g., athletes, the aged, those with cardiovascular diseases, etc.).
