| 摘 要： | 采用径向基函数（ＲＢＦ）神经网络作为室性早搏（ＰＶＣ）的检测器，将ＱＲＳ波的模板以及其他不同物理意义的特征参数综合在一个检测网络中，构成一种由Ｇａｕｓｓ函数和Ｓｉｇｍｏｉｄ函数作为隐层点基函数的混合型ＲＢＦ网络，并且给出确定网络结构参数的方法。用ＭＩＴ心电数据库对算法进行验证，单层心电信号的室性早搏检出率达到９８．４６％。

| Abstract: | Detecting premature ventricular contraction (PVC) is one of the main tasks in electrocardiogram (ECG) arrhythmia analysis. This paper presents a PVC detection method based on radial basis function (RBF) network. This paper combines the prototypes of QRS complexes and some other features into a kind of hybrid RBF network with Gauss and Sigmoid basis function in hidden nodes, and presents a method to determine its structural parameters. The differences among patients are considered in constructing the hidden nodes using self organizing clustering algorithm and fuzzy logical inference, so that the supervised training processes for each record are unnecessary. The detection rate reaches 98.46% using single lead signals from MIT arrhythmia database. |
