摘　　要：运动心电信号是反映运动时人体心脏负荷状况的重要信息，准确表述运动心电信号特征对于更好评价运动负荷实验是很有意义的，介绍了维格纳时频分析的原理与算法实现，将维格纳分布应用到运动心电信号的分析中，得到一些有益的结论，在时颇平面上研究运动心电信号特征变化是一个较好的途径。Exercise ECG indicates information about tbe heart load status in the exercise test,It is very significant to represent the characteristics of the exercise ECG for evaluating the exercise load test- This article introduces the principle of Winger-Ville Distribution time-frequency analysis and its implementation. By app1ybe this method to ana1yse Exercise ECG, some results were acquired. It is a promising method to do research of the Exercise ECG in the time-frequency plane.
