基于Wigner-Ville分布的心电信号时频分析
The time-frequency analysis of ECG signals based on Wigner-Ville distribution
摘要
Abstract
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.关键词
