Authors:Platisa, M. M., Nestorovic, Z., Damjanovic, S. and Gal, V.
"We found that all linear and non-linear HRV measures change in different direction in acute and chronic AN. Acute AN is characterized by decreased HR and increased HRV. In chronic AN, HR is increased, HRV reduced and the difference between awake and sleeping values is high. "
