Problems solved by technology

People are more familiar with the former because there was an electrocardiogram first and then a vector heart diagram in history; the operation of the vector heart diagram machine in the past was complicated, and it was not as simple as the traditional electrocardiogram machine and could continuously trace the heartbeat; the lead of the traditional electrocardiogram and the vector heart diagram The systems are different, and the depicted graphics cannot be compared with the same source; so the value of VCG has not been properly recognized, promoted, popularized, and developed healthily

Embodiment 1

[0062] 1. Formation of space center vector ring:

[0063] The heart is a three-dimensional, hollow, solid organ. The generation of cardiac bioelectricity comes from the conduction system of the heart and the electro-chemical diffusion of the myocardium. The countless instantaneous center vectors formed by it are distributed in the three-dimensional space. If the farthest ends of the instantaneous vectors are connected to each other, a three-dimensional ring of space trajectory is formed, which is called a space center vector ring or a three-dimensional center vector ring ( Figure 13). The middle ring in Fig. 13 represents the three-dimensional center vector ring, F, H, S represent the forehead, horizontal, and lateral three plane center vector rings generated after the first projection, and V1 and V5 represent the second projection. The electrocardiogram of the two-lead axis.

[0064] 2. The formula for calculating the amplitude of the space ECG vector:

[0065] ...

Embodiment 2

[0077] A method for realizing a three-dimensional image electrocardiogram. The steps include: establishing a three-dimensional coordinate liner, a cross plate composed of lines, flat plates, colors, light, etc. as a "three-dimensional liner"; The heart bushing is placed on the annulus of the three-dimensional space vector. Synchronous or selective sampling, display, observation, editing and tracing are used for 1-78 leads. "Three-dimensional lining" is a prior art, and the patent No. 98117316.0 is titled "Imaging method and imager for three-dimensional electrocardiogram", and this patent has a characteristic description of "three-dimensional lining".

[0078] A method for realizing a three-dimensional image electrocardiogram, the steps include providing a set of leads, that is, 16 electrode wires (15 channels) input lead system including Frank's 7 electrode system and 10 electrode wires of the traditional 12-lead electrocardiogram, wherein Frank The positive pole of the Y axi...

Embodiment 3

[0089] As shown in Figure 1, in the past, the anatomical morphology and electrocardiology of the heart belonged to two separate research fields, such as B-ultrasound and electrophysiology. The object of the present invention is to restore the three-dimensional anatomical structure of the heart and the three-dimensional electrocardiogram into one, closely combine the three-dimensional electrocardiogram in three-dimensional space and the anatomical structure of the virtual heart in three-dimensional space, and observe and diagnose with images and / or images. heart disease. The so-called visualization, intelligence, graphics, imaging, and automatic diagnosis of the structure and function of the heart. Its significance lies in that it is clear at a glance, and a picture is worth a thousand words. That is, three-dimensional, all-round, and intuitively reflect the phase relationship between cardiac bioelectrical activity and actual heart position; the forward and reverse time-phase ...

Abstract

The invention relates to a three-dimension picture electrocardiograph, and relative application, wherein it has 16 electrode lines parallel input 5 channels Einthoven-Goldberger-Wilson and Frank guide system; the Frank electrocardiograph collects electrocardiograph signal to be treated by computer, computer assist design, to realize multi-dimension, synchronous, and real-time conversation; storing at 24h, synchronizing 1-78 guides or selectively washing electrocardiograph; generating database, 12 electrocardiographs, orthogonal electrocardiograph, vector electrocardiograph, etc.

Description

technical field [0001] The present invention relates to a three-dimensional image electrocardiograph and its realization method, which are a medical examination and diagnosis method and instrument, namely a three-dimensional imaging electrocardiograph (3DI-ECG) for modern medical diagnosis of cardiac bioelectric activity. It belongs to the field of medical diagnostic instruments. Background technique [0002] Three dimensional imaging electrocardiogram (3DI-ECG) has the same essence as traditional electrocardiogram (Electrocardiogram, ECG), both of which are graphs of cardiac bioelectrical activity traced from the body surface. It is only due to the different stages of technological development (ie: string type→coil rotation type→direct tracing type→cathode ray type→computer); different viewing angles for the same object from the time / space domain; different ECG lead systems; processing Different methods; different forms of expression; different cognitions, etc., make the r...
