[0002] Heart-related diseases are complex and diverse. Currently, the alarm information of abnormal ECG data in the monitoring system only displays the name, such as anterior myocardial infarction, lateral myocardial infarction, ventricular tachycardia, atrial tachycardia, etc., and cannot intuitively display the specific location of the heart lesions. Therefore, a heart model that can synchronously display the location of heart lesions is needed to facilitate medical staff to quickly understand the patient's heart condition and improve the doctor's diagnostic efficiency. Summary of the invention

[0003] In order to solve the above problems, the present invention proposes a three-dimensional cardiac model and a method for displaying the location of a lesion, a terminal device and a medium.

[0005] Furthermore, the three-dimensional heart model is constructed based on medical imaging data of a healthy human heart.

[0006] Furthermore, the three-dimensional model of the heart was constructed using Cardiac Moduler 3D software, by extracting the component structure of each layer of medical image slice data and stacking the layers in sequence.

[0007] Furthermore, heart diseases include anterior myocardial infarction, posterior myocardial infarction, atrial fibrillation, ventricular fibrillation, atrioventricular block, premature beats, tachycardia and sick sinus syndrome.

[0008] Furthermore, when marking corresponding coordinates in the three-dimensional heart model, the corresponding coordinates are marked as dark dots.

[0019] In this embodiment, the heart three-dimensional model is constructed based on the medical imaging data of a healthy human heart. The CardiacModuler3D open source software is used during the construction to extract the heart three-dimensional model from the collected medical imaging data of a healthy human heart. The specific process is to extract the component structures (such as blood vessels, atrial muscles, ventricular muscles, etc.) of each layer of medical imaging slice data respectively, and stack the layers in order to generate the corresponding heart three-dimensional model, such as Figure 2 shown.

[0020] S2: Encode all types of heart diseases respectively, obtain the coordinates of the lesion position corresponding to each heart disease in the three-dimensional heart model, and record the corresponding relationship between the code and the coordinates of each heart disease.
