心电波形的层次结构及其描述方法

THE HIERARCHICAL STRUCTURE OF THE ELECTROCARDIOGRAM WAVE FORM AND ITS DESERIPTION METHOD

针对心电波形,本文提出了一种基于层次结构的特征抽取和描述方法。在基线拟合、峰谷点识别后,通过在不同层次上对心电波形的划分,形成诸如波元、波群、不可分波群、特殊波群的层次结构。对于每一层次上的特征抽取与模式描述,文中均给出了具体方法和步骤。最后给出了计算实例。这种心电波形的层次描述方法简明有效,是进一步实现心电波形模式识别与疾病诊断的基础。

For the electrocardiogram wave form, based on the hierarchical structure, this paper presents a characteristic sample and description method. After the agreement of the base line as well as the identification of the wave crest and wave trough points, establish the hierarchicical structure for such wave as wave unit, wave complex, indivisible wave complex as well as special waves. In the paper, the concrate methods and steps for characteristic sample and model description on each leyer have been presented. This method is simple and efficient, which makes a basis for further improving the transverse identification of the wave form and for disease diagnosis.
