中文摘要：

正常的心脏中出现的混沌、心率过速与心肌组织中出现螺旋波有关，研究了一种七维心脏一血液耦合动力系统模型．首先通过线性负反馈对系统的参数进行了辨析，基于混沌反控制方法，使非混沌的心脏系统混沌特性加强，计算了系统输出信号的Lyapunov指数，为反馈信号幅度提供依据．数值计算模拟表明该方法的可行性，希望可以为心脏病的治疗和修复提供帮助信患．

英文摘要：

The chaos and tachycardia happened appears in normal heart are related to spiral wave happened in myocardial tissue. A dynamic system model of seven-dimensional heart-blood coupling was investigated in this paper. First by using the linear negative feedback control, the unknown parameters of the system were identified. Then the chaos anti-control was used to make the identified system with non-chaotic behavior chaotic one. The Lyapunov exponents of output signals were estimated in order to offer important information for the amplitude of feedback control. The numerical simulation results showed that this method was feasible and it was expected to give useful information in curing heart diseases.
