基于Wigner-Ville分布的心电信号时频分析,采用美国麻省理工学院的MIT-BIH数据库中提供的正常窦性心律数据和心律失常数据,运用Matlab软件编程,做出了人体心电信号的Wigner-Ville分布.结果表明：通过编程仿真,可得出较好的心律正常和心律失常的Wigner-Ville分布的三维图和等高线图.对比分析它们的三维图和等高线图,能准确显现出非平稳信号的特征变化.可以为现代临床诊断提供重要的医学信息.

Aim at the time-frequency analysis of eelectrocardiograph（ECG） signals based on Wigner-Ville Distribution.The test data come from MIT-BIH normal sinus rhythm database and MIT-BIH supraventricular arrhythmia database.The author makes the Wigner-Ville distribution of ECG using matlab software.The study arrives at the better three-dimensional maps and contour maps of Wigner-Ville Distribution of normal heart rhythm and arrhythmia by programming and simulation,and show the characteristics changes of non-stationary signals by analysing and comparing the three-dimensional maps and contour maps.It can provide important medicine message for clinical diagnosis.
