| 摘 要： | 从理论上研究了时频分析方法中的短时傅立叶变换和W inger-V ille分布,并对正常心电信号和心室纤维颤动心电信号进行了仿真试验.仿真结果表明,利用时频分析方法研究时变的非平稳信号的特征变化是有效的,可以为临床诊断提供更充分的诊断依据.

| Abstract: | STFT and Winger-Ville distribution were analyzed,and the simulations of normal ECG and ventricular fibrillation ECG were conducted.The simulation results show that it is effective to use time-frequency analysis to study characteristic changes of time variant non-stationary signals,which can provide more diagnostic evidence for clinical diagnosis. |
