摘要
根据高频心电信号的发生机制，本文讨论了把维格纳分布用于分析这种信号的优点。运用注射脑垂体后叶素（ｐｉｔ）建立家兔心肌缺血模型，用维格纳分布系统地分析了家兔缺血产生、缓解过程中心电波形的变化。观察到一些有用的规律，证实维格纳分布为高频心电信号研究展示了新前景。
Accouding to mechanism of generation of high-frequency electrocardiac signal (HFECG), this paper discussed the advantages of WignerVille distribution(WVD)in HFECG analysis.A model of rabbit myocardial ischemia was established by injecting pitressin,and WVD was used in systemic analysis of HEECG during attack and remission of myocardial ischemia.Some useful pattens were recognized, suggesting feasibility of WVD application in HFECG analysis.
