| 摘 要： | 针对混沌在心脏系统中的研究，利用Lyapunov特性指数来进行心电信号的数据分析．由混沌检测系统的Lyapunov特性指数的计算方法，通过重构相空间，对健康人和5种类型心脏病人的数据作为样本进行对比分析．仿真结果表明，采用最大Lyapunov特性指数可以判断健康心脏和病态心脏的混沌性差异，为早期心脏疾病的辅助诊断提供了依据．

| Abstract: | Chaos is studied in the research of heart system. Data analysis of ECG signals is carried out utilizing Lyapunov characteristic exponents. The data of healthy people and three heart disease patients are compared and analyzed based on the computing method of Lyapunov characteristic exponents in chaos detection system and phase space reconstruction. Simulation results indicate that the chaos differences of healthy heart and pathological heart are identified, using Lyapunov characteristic exponents. The study provides auxiliary diagnosis for early stare cardiac patients. |
