Abstract

A method and device for quantitative analysis of pathological features of electrocardiographic data, relating to a method and device for quantitatively extracting multiple pathological features of a dynamic cardiac electrical activity system and an abnormal analysis method and device for cardiac electrical signals, belonging to the field of heart disease data feature mining and used to solve The problem of digging out more and richer dynamic pathological features in the electrical activity of the cardiac nonlinear system, the key point is to have the ability to extract the quantitative indicators of the cardiac dynamic pathological features inherent in the dynamic data of the nonlinear system of cardiac electrical activity by means of heterogeneity analysis Step, the heterogeneity analysis refers to the inhomogeneity and complexity analysis of the dynamic data of the nonlinear system of cardiac electrical activity in the process of spatial distribution and time deduction, and the effect is: the obtained information can present The dynamic pathological characteristics of the nonlinear system of cardiac electrical activity.

Description

technical field [0001] The invention belongs to the field of heart disease data feature mining, and relates to a method and device for quantitatively extracting multiple pathological features in a dynamic cardiac electrical activity system, and a method and device for abnormally analyzing cardiac electrical signals. Background technique [0002] Cardiovascular diseases, especially heart diseases caused by myocardial ischemia, have brought many adverse effects on human health. The World Health Organization pointed out: Among the top ten diseases that are most likely to cause human death, ischemic heart disease ranks first. In my country, the number of deaths due to cardiovascular disease ranks first among various diseases every year; among them, many patients suffer from myocardial ischemic coronary heart disease, but have no obvious clinical symptoms. Although modern coronary heart disease treatment technology has been continuously improved, and the cure rate of ischemic he...
