Problems solved by technology

[0003]However, the voltage value of ECG is greatly affected by the patient's physical factors (such as fat and thin, the position of the heart in the chest, and the geometric data of the heart), but these physical factors It is not the pathological factor of the patient's cardiomyopathy, so these physical factors will interfere with the clinical doctor's interpretation of the voltage value of the electrocardiogram, thereby affecting the accuracy of the voltage value, and in severe cases, it can cause clinically wrong diagnosis

[0177] Simulation Calculation of QRS Wave Electrocardiogram in Experimental Example 1 with Different Arrival Blocks

[0178] In this experiment example, a healthy human body was selected (echocardiography showed no abnormality), and the specific physical data included: the chest width measured by imaging (CT) was 309.6mm, the chest thickness was 207.8mm, and the transverse orientation of the heart (see image 3 and description) 0.407, heart longitudinal orientation (see Figure 3 and description for measurement method) 0.646, the thickness of the cardiac interventricular septum was 7 mm, the thickness of the left ventricular posterior wall was 7 mm, and the end-diastolic diameter of the left ventricle was 42 mm.

[0179] Utilize the method and equipment in the embodiment of the present invention to obtain their target surface mesh models respectively, and then assume that they perform the calculation of the body surface potential respectively under the condition of normal heart ...

[0182] Experimental Example 2 Diagnostic Effect Verification

[0183] In this experimental example, for 60 patients with amyloid cardiomyopathy and 60 healthy people, use the auxiliary diagnostic equipment for cardiomyopathy in the embodiment of the present invention and the traditional Sokolow index to carry out the diagnosis of cardiomyopathy for all patients and all healthy people respectively. Judgment verification. The ROC curve of the auxiliary diagnostic equipment of cardiomyopathy and Sokolow index in the embodiment of the present invention is as follows Figure 9 shown. It can be seen that the auxiliary diagnostic equipment for cardiomyopathy in the embodiment of the present invention has a high diagnostic effect, and it is obviously due to the traditional Sokolow index.

[0184] Those skilled in the art can clearly understand that for the convenience and brevity of the description, the specific working process of the above-described system, device and unit can refe...

Abstract

The invention discloses auxiliary diagnosis equipment and device for cardiomyopathy and a computer readable storage medium. The equipment comprises a memory and a processor; the memory is used for storing program instructions; the processor is used for calling a program instruction, and when the program instruction is executed, the processor is used for executing the following operations: receiving first electrocardio-related body data, a first electrocardio-related biological constant and a first actual target voltage value of a target patient, transforming the standard surface grid model by using the first electrocardio-related body data to obtain a target surface grid model corresponding to the target patient which reflects body factors of the target patient but does not reflect pathological factors of cardiomyopathy of the target patient, obtaining a first body surface potential, obtaining a first simulation target voltage value according to the first body surface potential, and acquiring a cardiomyopathy diagnosis result of the target patient by using the first simulated target voltage value and the first actual target voltage value. According to the method, the influence of body factors of a target patient on cardiomyopathy judgment can be well eliminated.

Description

technical field [0001] The present invention relates to the technical field of electrocardiogram simulation, and more specifically, to an auxiliary diagnosis device, device and computer-readable storage medium for cardiomyopathy. Background technique [0002] Cardiomyopathy is a group of heterogeneous myocardial diseases caused by abnormalities in the mechanical and electrical activity of the heart caused by different etiologies, manifested by inappropriate hypertrophy or dilation of the ventricles, such as myocardial fibrosis, myocardial amyloidosis, left ventricular hypertrophy, and myocardial fatty infiltration Wait. Electrocardiogram (ECG, electrocardiogram) is a technique that uses an electrocardiograph to record from the body surface the electrical activity change patterns produced by each cardiac cycle of the heart. Among them, the voltage value of the electrocardiogram is the most basic information provided by the electrocardiogram for clinical doctors, and it is of...
