title: [Analysis of Lyapunov exponents of heart rate variability in diabetics].
abstract: This paper presents an analysis of Lyapunov exponents of ten normal persons and ten patients with diabetes mellitus by the definition of the Lyapunov exponents, the length evolution and the area evolution. The results show that the Lyapunov exponent of diabetic is clearly lower than that of normal. It can indicate the diabetic with less number of electrocardiographic data.
