Problems solved by technology

[0007] Although there are some ECG detection equipment specially designed for individuals on the market, the structure is complex and the operation is very troublesome. More importantly, once the electrode position is placed incorrectly, the obtained ECG data will be inaccurate. The diagnosis and treatment basis of the disease will bring unpredictable and serious consequences

Embodiment Construction

[0035] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Such as figure 2 As shown, the ECG electrode connection discrimination method of the present invention comprises the following steps:

[0037] (1) Simplify the judgment of the electrode position.

[0038] First of all, before judging whether the electrode positions in the three-lead ECG detection process are wrongly connected, considering that the complex arrangement and combination of seven electrode misplacements is too large, it is necessary to simplify the electrode position judgment. That is, firstly, it is ruled out that the position of the ground electrode RL away from the remaining six electrodes is wrongly connected, refer to figure 1 It can be seen that the seventh electrode RL is far away from the other six electrodes, it is very easy...

Abstract

The invention discloses a method for judging the connection of three-lead ECG electrodes, which comprises: (1) collecting three-channel ECG standard signal segments and ECG training signal segments; The linear regression model of the two channel signals; (3) according to the correlation coefficient method, the characteristic value is extracted as the ECG training sample, and the gradient descent method is used as the optimization direction to carry out supervised learning to obtain the weight ratio of each layer of the artificial neural network; ( 4) Restore the system model. The present invention firstly simplifies the wrong connection situation, and then utilizes the linear regression model and the correlation coefficient method to extract the characteristic value of the ECG signal, and finally obtains the discrimination model of the wrong connection of the ECG electrode through the study of the artificial neural network. Performing wrong connection judgment greatly improves the efficiency and accuracy of the judgment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a method for judging the connection of three-lead ECG electrodes. Background technique [0002] The medical equipment used in existing hospitals has a complex structure and cumbersome operation steps, requiring professionals to operate. It is difficult for individual consumers to use it in community medical care, elderly care, and even remote diagnosis and treatment for a long time. Especially complex equipment and numerous connections will cause psychological pressure and tension of the patient, which may affect the patient's physical condition, causing a certain gap between the data obtained from the diagnosis and the real situation, which may affect the correct diagnosis of the disease . [0003] Dynamic electrocardiogram is one of the important methods for the prevention and diagnosis of heart disease. Taking heart disease common in middle-aged and elderl...
