Abstract

The invention relates to the technical field of measurement for diagnosis, and provides an electrocardiogram and pulse wave relation analysis method and a method and device of fusion analysis based on the electrocardiogram and pulse wave relation analysis method. The electrocardiogram and pulse wave relation analysis method includes the steps that step1, obtained electrocardiogram signals and pulse wave signals of a known patient are preprocessed respectively, and the preprocess comprises base line horizontal-moving and denoising; step2, the preprocessed electrocardiogram and the pulse wave are visually showed in a two-dimensional and/or three-dimensional image; step3, characteristics of the electrocardiogram and the pulse wave are extracted; step4, the characteristics of the electrocardiogram and the pulse wave are compared and analyzed to obtain the mutual relation of the characteristics of the electrocardiogram and the pulse wave, and fusion analysis inspection is carried out according to the mutual relation of the characteristics. Compared with analysis of singular signals, the accuracy rate of classification of results is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of measurement for diagnostic purposes, in particular to a method and device for analyzing the relationship between an electrocardiogram and a pulse wave and based on the fusion analysis. 【Background technique】 [0002] An electrocardiogram is a graph that records the electrical signals generated by the heart cycle and draws them in a prescribed format. The pulse wave is formed by the pulse of the heart propagating along the arterial vessels and blood flow to the periphery. Although the forms produced by the two are different, the source of both is the heart, so it is of great significance to study the mutually exclusive, consistent and complementary relationship between the two. [0003] ECG has been widely used in the clinical diagnosis of cardiovascular diseases. In recent years, in order to reduce the workload of doctors in remote monitoring and medical examination centers, the demand for automatic E...
