Embodiment Construction

[0043] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0044] Firstly, the theoretical basis of the 18-lead dynamic electrocardiogram analysis method and system based on Wilson leads in the embodiment of the present invention will be described below. Theoretical basis of the present invention originates from electrocardiogram Einstein's triangle theory (galvanic couple-volume conduction theory), electrocardiographic vector diagram - electrocardiogram orthogonal electrocardiogram and electrocardiogram Figure II Basic theory of subprojection. ECG Figure II Subprojection ...

Abstract

The invention provides a method and a system for analyzing 18-lead dynamic electrocardiograms on the basis of Wilson lead. The method includes arranging 10 electrode slices at preset positions of the body surface of a tested person, acquiring electrocardiogram signals of the tested person by the aid of each electrode slice and processing the electrocardiogram signals to obtain corresponding electrocardiogram data; acquiring 12-lead electrocardiogram data of the tested person according to the electrocardiogram data of the tested person; computing X-axis, Y-axis and Z-axis data on the basis of Wilson lead systems according to the 12-lead electrocardiogram data of the tested person; deriving lead data for representing the left ventricle of the tested person on the basis of the Wilson lead systems and deriving lead data for representing the right ventricle of the tested person on the basis of the Wilson lead systems; generating the 18-lead electrocardiograms of the tested person. The method and the system have the advantages that 12-lead electrocardiograms can be recorded and synchronized by the aid of the improved Wilson lead systems, and the 18-lead electrocardiograms can be calculated from the 12-lead electrocardiograms.

Description

technical field [0001] The invention relates to the technical field of electrocardiogram monitoring, in particular to an analysis method and system for an 18-lead dynamic electrocardiogram based on Wilson leads. Background technique [0002] The heart is a three-dimensional organ, and the electrocardiographic vector generated at each moment during the excitation process has a certain spatial position, that is, the three-dimensional relationship of up and down, left and right, and front and back reflects this three-dimensional vector, which is called a space vector. Because the ECG vector can display the phase relationship of the ECG, it makes up for some deficiencies in the diagnosis of the ECG. Both the ECG and the ECG vector are the main low-frequency components in the ECG information collected from the body surface, and they have a common theoretical basis. It's just that the lead system and the way of expression are different. [0003] In the conventional electrocardiog...
