Abstract

The invention provides a method and system for locating the location of myocardial ischemic lesions, a storage medium and a terminal, comprising the following steps: preprocessing the magnetocardiogram data set collected by a multi-channel magnetocardiograph, obtaining the T wave band heart rate after the mean value Magnetic map data set; Based on the magnetocardiogram data set of the T wave band and the magnetic field strength and the channel position obtained by each channel of the multi-channel magnetocardiograph, obtain the isomagnetic map and the current density map of the T wave band; Based on the isomagnetic map and the current density map, feature parameters related to the myocardial ischemic lesion location are extracted; according to the feature parameters, the myocardial ischemic lesion location is judged. The myocardial ischemic lesion location method and system, storage medium and terminal of the present invention analyze the signal characteristics of the magnetocardiogram, discover the distribution law of the characteristic parameters, and assist in realizing the myocardial ischemic lesion according to the characteristic parameters sensitive to the myocardial ischemic location Location targeting.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and system for locating the position of a myocardial ischemic lesion, a storage medium and a terminal. Background technique [0002] Myocardial ischemia is a common heart disease, and its morbidity and mortality have been increasing year by year in recent years. The location of myocardial ischemia is of great value in understanding the severity of the disease, predicting the development of the disease, and specifying follow-up medical plans. Traditional cardiac imaging methods have certain limitations in the localization of myocardial ischemia. At present, cardiac tomography (CT) or coronary angiography is commonly used clinically to estimate the lesion location. Such methods are highly invasive, and patients need to bear the side effects of X-rays or angiographic contrast agents. Especially for myocardial ischemia patients with renal dysfunction, the ...
