I proposed a method to analyze heart rate variability in the respiratory phase domain and illustrated its advantages for the evaluation of autonomic nervous activity. In addition, I proposed a model for cardio-vascular system which demonstrates statistical physical properties of heart rate variability such as multifractality. Literature 1) K. Kotani, M.
