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 misconnection of leads used in Wilson standard 12-lead ECG includes the following steps:

[0032] S1: According to Wilson standard 12-lead system, such as figure 1 As shown, the conversion matrix T that converts the lead value vector into the electrode voltage value vector under the lead system is calculated L2E , And the conversion matrix T that converts the electrode voltage value vector to 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 the limb leads can be derived from the II and III leads, the lead vector L=(ⅡⅢV1V2V3V4V5V6) T , That is, the number of independent leads is 8, 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

[0036] III=E F -E LA

[0037] V i = E Ci -E WCT

[0038] The conve...

Embodiment 2

[0050] In this embodiment, it is assumed to be a complicated misconnection method under the Wilson standard 12-lead system: F and C1 are connected reversely, and LA and C2 are connected reversely. The correcting steps are basically the same as those in the first embodiment above, and will not be repeated. The difference is that in step S3, only the following permutation matrix T' PMT Replace the permutation matrix T of the first embodiment PMT :

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

Embodiment 3

[0056] A method for correcting misconnection of leads used in the ECG of the EASI lead system includes the following steps:

[0057] S1: According to the EASI lead system, such as image 3 As shown, the conversion matrix T of the lead value vector converted into the electrode voltage value vector under the lead system is calculated. L2E , And the conversion matrix T which converts the electrode voltage value vector to the lead value vector" E2L , The specific method is:

[0058] According to the EASI lead ECG connection mode, define the lead vector L”=(ESASAI) T , The electrode potential vector E"=(E E E A E S E I ) T , According to the calculation method of EASI lead:

[0059] ES=E E -E S

[0060] AS=E A -E S

[0061] AI=E A -E I

[0062] It is possible to derive the conversion matrix T which converts the lead value vector to the electrode voltage value vector" L2E , And the conversion matrix T which converts the electrode voltage value vector to the lead value vector" E2L as follows:...

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 present invention relates to the medical field, in particular to a method for correcting wrong connection of electrocardiogram leads. Background technique [0002] Electrocardiograph or Holter is an instrument used to record the physiological electrical signals generated during heart activity. Due to the mature, reliable, easy-to-operate, moderate price, and no harm to patients, electrocardiographs have become commonly used in clinical diagnosis and scientific research. Medical electronic equipment. The premise of ensuring the accuracy of ECG data is that the lead must be connected to the correct position. However, in the actual ECG examination, due to the negligence or lack of experience of the operating technician, it is very likely that the lead is connected incorrectly, resulting in an error. ECG recording. Usually, the diagnosing doctor will re-examine the patient after seeing such an ECG record. In addition to wasting manpower and material resou...
