摘　　要：In this paper, we introduce a nonlinear method named as "Complexity Analysis" by which we study the chaotic and other behavior in heart rate of the patients suffer from AMI, STSDS and VPB, or normal healthy subjects. The results show that the nolinear parameter-complexity reflects the dynamic state of heart. It can be used to measure the complexity of biologic systems quantitatively. It is possible to use such a method to analyze and diagnose cardiovascular disease in clinics.In this paper, we introduce a nonlinear method named as 'Complexity Analysis' by which we study the chaotic and other behavior in heart rate of the patients suffer from AMI, STSDS and VPB, or normal healthy subjects.
