Application: It is used to extract the human electrocardiographic wave group for morphological and rhythm analysis for clinical diagnosis and research.

The three-dimensional electrocardiograph supports Wilson and Frank two-lead systems, and can collect conventional twelve, fifteen, eighteen, and orthogonal lead ECGs. The three-dimensional electrocardiograph also supports the simultaneous acquisition of these two lead systems. One acquisition can obtain a three-dimensional electrocardiogram (vector) map, a twelve-lead electrocardiogram, a twelve-lead electrocardiogram + a right chest lead or a posterior wall lead electrocardiogram. , Orthogonal electrocardiogram, time electrocardiogram vector graph, continuous electrocardiogram vector graph, change direction electrocardiogram vector graph and many other graphics.

According to the "second projection theory" in electrocardiography, the electrocardiogram is formed by the secondary projection of the three-dimensional ECG vector loop. However, it is easy to lose some important ECG information during the projection process, such as the sudden turning, overlap, erosion and bulge of QRS vector ring body, and this information is extremely important for the diagnosis of coronary heart disease, especially myocardial infarction. Three-dimensional ECG makes up for these shortcomings of conventional ECG in diagnosis, and eliminates the "blind zone" of conventional ECG and planar ECG vector diagrams and the parts that overlap due to the perspective. Therefore, when the electrocardiogram is suspicious or cannot be clearly diagnosed, it is absolutely necessary to make a comparative analysis of the three-dimensional electrocardiogram.

A large number of clinical studies have shown that the three-dimensional electrocardiograph can diagnose and differentiate myocardial infarction with bundle branch block, bundle branch block and multi-beam block, ventricular hypertrophy, atrial arrhythmia with indoor differential conduction, and ventricular arrhythmia. Diagnosis, localization of the origin of ventricular arrhythmias (diagnosis and differentiation of endocardial and epicardial ventricular premature beats), and diagnosis and localization of preexcitation syndrome also have obvious advantages over conventional ECG.

According to the requirements of the majority of electrocardiographers, the stereo electrocardiograph produced by our company has designed a series of original functions:

1. Up to 26 channels of ECG signals can be displayed and printed simultaneously;

2. Unique heartbeat number function, can choose heartbeat for analysis;

3. Overlay printing function: The ECG vector loops of multiple heartbeats can be displayed and printed on top of each other to clearly compare the differences between normal and ectopic heartbeat (color display) ECG vector loops.

4. Color printing function: Support different colors of P ring, QRS ring, T ring, and QRS ring at the beginning, middle and end of the display, the above functions can be customized;

5. Color stereo vector ring body that can rotate at any angle of 360 °, supports automatic rotation and mouse drag rotation;

6. After the acquisition of ordinary twelfth, fifteenth and eighteenth lead ECGs, planar ECG vector images and stereo ECG vector images can be reconstructed;

7. Abundant parameter indicators provide more comprehensive diagnostic data for clinicians;

8. Rich report templates for clinicians to choose freely;

9. The diagnostic standard from the three-dimensional electrocardiogram is accurate and unique, and the three-dimensional electrocardiogram that realizes all-round and full-view observation makes the diagnosis more objective, comprehensive, detailed, intuitive, accurate and practical.

The three-dimensional ECG vector map analysis system realizes a comprehensive and full-view observation of the electrocardiographic characteristics of the atria, ventricular depolarization and repolarization at various levels, which is helpful for the diagnosis of common cardiovascular diseases and assesses the prognosis and risk of arrhythmia in patients.

The three-dimensional electrocardiograph supports two types of lead systems, Wilson and Frank. In clinical applications, it can replace standard ECG machines for standard 12-lead, 15-lead, 18-lead, and orthogonal-lead ECG examinations. The three-dimensional electrocardiograph also supports the simultaneous acquisition of these two lead systems. One acquisition can obtain three-dimensional electrocardiogram (vector), 12-lead ECG, 12-lead ECG + right chest lead (V3R, V4R, and V5R ) Or posterior wall leads (V7, V8, and V9), ECG, orthogonal ECG, time ECG vector, continuous ECG vector, and changing direction ECG vector. The three-dimensional electrocardiogram includes all the functions of the ordinary electrocardiogram. The three-dimensional electrocardiogram can complete the tasks that the ordinary electrocardiogram cannot complete, such as the multiple heartbeat overlap function of the ECG vector loop described above, the running speed, direction and orientation of each part of the QRS loop. These functions of the stereo electrocardiograph make it far beyond the conventional electrocardiogram, and provide clinicians with broader diagnostic and analysis ideas.

As a multi-domain stereo electrocardiogram (vector) diagram analysis and diagnosis comprehensive system, the stereo electrocardiograph contains a number of indicators and functions in the field of electrocardiography diagnosis, which enables clinicians to comprehensively evaluate the state of cardiac electrical agitation and myocardial disease. , Improved the sensitivity, specificity, accuracy and practicality of ECG diagnosis, more convenient for the classification, identification, diagnosis and treatment of clinical diseases.
