Embodiment

[0021] This embodiment is a device for making models of ventricular tachycardia and atrial tachycardia, such as figure 1 As shown, it includes an electrode catheter 1 , a signal stimulation source 2 and an electrocardiographic monitoring device 4 for detecting a test subject 3 . The test body is a miniature pig or a medium-sized dog. In this embodiment, a Beagle dog with a body weight of 10-15 kg is used.

[0022] The method for making models of ventricular tachycardia and atrial tachycardia, the steps are as follows:

[0023] Step 1: Anesthetize the subject and connect the subject to the ECG monitoring device;

[0024] Step 2: Insert the electrode catheter into the common vein of the experimental subject. The process of inserting the electrode catheter into the experimental subject is: bluntly dissect the common jugular vein of the experimental subject, ligate the common jugular vein, cut a 2mm small opening below the ligation point, and insert the electrode catheter into th...

Abstract

The invention relates to a device and a method of fabricating a ventricular tachycardia (VT) model and an atrial tachycardia (AT) model. The device comprises an electrode catheter, a signal stimulus and an electrocardiogram monitoring device detecting a test subject. The electrode catheter is connected on the signal stimulus. In the operating process, the test subject is anaesthetized and connected with the electrocardiogram monitoring device, the electrode catheter is inserted into a cardinal vein of the test subject to the atrium, stimulus signals are sent out to the atrium, the AT model is obtained through the electrocardiogram monitoring device, the electrode catheter continues to be inserted downward to the ventricle, stimulus signals are sent out to the ventricle, and the VT model is obtained through the electrocardiogram monitoring device. The method has the advantages of being simple in operating process. Compared with fabricated model data obtained with a pharmic method, the model data with the method better fits pathologic conditions caused by abnormal electrocardiogram signals clinically, and the atrial heartbeat frequency and the ventrical heartbeat frequency can be effectively separated.

Description

technical field [0001] The invention relates to a method for making a medical data model, in particular to a device and method for making animal models of ventricular tachycardia and atrial tachycardia. Background technique [0002] Ventricular tachycardia and atrial tachycardia are common clinical arrhythmia diseases. In order to study related ventricular and atrial tachycardia diseases, it is necessary to use a suitable experimental platform for electrophysiology, biochemistry, and molecular biology. Studies in various aspects such as biology, histology, and pathology. [0003] At present, the existing models for replicating ventricular and atrial tachycardia are mainly based on drug stimulation, which involves intraperitoneal injection of acetylcholine or norepinephrine drugs, and the drug stimulation causes rapid heartbeat to replicate rodent models. This type of model is mainly caused by drugs, which is inconsistent with the pathological conditions caused by abnormal c...
