基于模糊灰色理论心电图评价可靠性

Reliability evaluation for dynamic electrocardiogram based on gray-fuzzy theory

为了改善各影响因素之间存在灰色模糊特征的动态心电图的评价可靠性,利用模糊灰色理论,构建基于模糊灰色理论18导联动态心电图评价可靠性模型,并通过样本对影响心电图系统可靠性各因素的分析,确立各隶属度函数,构造特征矩阵作为灰聚类的评判依据,从而减少了聚类过程的主观性,使得评价的准确率提高.经过临床实验研究证明,利用该方法对心电图进行评价,其评价精度、可靠性较传统方法显著提高,为该技术的实际应用奠定了理论与临床实验基础.

The reliability s evaluation method for 18-channel dynamic electrocardiogram(ECG) is studied based on the gray-fuzzy theory.According to the gray-fuzzy feature among factors which affect ECG and fuzzy mathematics,a characteristic matrix is constructed to evaluate the ECG s reliability based on the gray-fuzzy theory using indicator s membership grade so as to decrease the subjectivity during gray-fuzzy clustering and therefore increase the accuracy of reliability s evaluation.The result shows that it is feas...
