Problems solved by technology

However, in the actual ECG collection process, especially during dynamic ECG collection, each electrode of some collection equipment uses the same patch electrode, and they are all connected to the patient's torso, and any lead may occur. indirect case
Moreover, with the development of remote ECG medical projects, sometimes the connection of the leads is completed by the patient's family members according to the instructions, and the situation of wrong connection of the leads is more complicated.
[0006] There is currently no solution for the complex misconnection of leads

Embodiment 1

[0031] A method for correcting lead misconnection used in Wilson standard 12-lead electrocardiogram, comprising the steps:

[0032] S1: According to the Wilson standard 12-lead system, such as figure 1 As shown, calculate the transformation matrix T that converts the lead value vector into the electrode voltage value vector under the lead system L2E , and the transformation matrix T that transforms the electrode voltage value vector into the lead value vector E2L , the specific method is:

[0033] According to the Wilson standard 12-lead ECG connection method, considering that other data of limb leads can be derived from leads II and III, the lead vector L=(ⅡⅢ V1 V2 V3 V4 V5 V6) is defined T , that is, the number of independent leads is 8, and the electrode potential vector E=(E F E. RA E. LA E. C1 E. C2 E. C3 E. C4 E. C5 E. C6 ) T , according to the calculation method of Wilson lead:

[0034] E. WCT =1 / 3*(E F +E RA +E LA )

[0035] II=E F -E RA

Embodiment 2

[0050] In this embodiment, it is assumed that it is a complex misconnection method under the Wilson standard 12-conductor system: F and C1 are reversed, and LA and C2 are reversed. The correcting steps are basically the same as those in the above-mentioned first embodiment, and will not be described again. The difference is that in step S3, only the following permutation matrix T' PMT Replacing the permutation matrix T of Embodiment 1 PMT :

[0051] T ' MPT = 0 0 1 0 0 0 0 0 0 0 1 ...

Embodiment 3

[0056] A method for correcting lead misconnection used in an EASI lead system electrocardiogram, comprising the steps of:

Abstract

The invention relates to the medical field and specifically relates to a method for correcting electrocardiographic lead misconnection. The method introduces a concept of an electrode displacement matrix and combines lead data calculation manners in different lead systems to map data generated from the misconnection into correct lead connection data. The method for correcting the electrocardiographic lead misconnection provided by the invention can be applicable to different complicated misconnection manners in multiple lead systems (such as Wilson, EASI, 15 leads and 18 leads), solves problems such as the misconnection between a chest lead and limb leads which cannot be dealt with by current methods, and plays an important role in increasing doctors' working efficiency and relieving doctor-patient relations in actual clinical applications.

Description

technical field [0001] The invention relates to the medical field, in particular to a method for correcting wrong connection of electrocardiogram leads. Background technique [0002] Electrocardiography or dynamic electrocardiography is an instrument used to record physiological electrical signals generated during heart activity. Due to its mature diagnostic technology, reliability, easy operation, moderate price, and no damage to patients, it has become a commonly used instrument for clinical diagnosis and scientific research. of medical electronic instruments. The premise of ensuring the accuracy of the ECG data is that the leads must be connected to the correct position. However, in the actual ECG examination, due to the negligence of the operating technician or lack of experience, it is very likely that the leads will be wrongly connected, resulting in erroneous results. ECG recording. Usually the diagnostician sees such an ECG record and will re-examine the patient. I...
