Abstract BACKGROUND: The authors investigated autonomic cardiac function in anorexia nervosa. METHODS: Forty-eight patients, who in the present or past met the DSM-III-R criteria for anorexia nervosa, and 16 normal control subjects participated in a standardized analysis of heart rate variability during supine and standing postures. RESULTS: Several heart rate variability parameters showed an inverse correlation to the present weight of the anorexic subjects. The values of the spectral power analyses were significantly (p < .01) lower in patients (n = 18) weighing less than 75\% of ideal weight when compared to the results found in the control group; however, the heart rate variability parameters of anorexic subjects with restored weight (n = 12) did not differ from those of the control subjects. CONCLUSIONS: The obtained results provide evidence for autonomic cardiac dysfunction in acutely ill anorexic patients. Further research is required to elucidate possible clinical consequences of these findings.
