Description

Technical Field

[0001] This invention relates to the field of medical facility technology, and in particular to a method, apparatus, electronic device, and storage medium for detecting malconnections in limb leads of an electrocardiogram. Background Technology

[0002] With the popularization of remote ECG networks, more and more clinical scenarios have emerged where ECG operation and ECG diagnosis are separated. In this scenario, due to the diverse professional backgrounds and insufficient proficiency of ECG operators, lead misconnection, especially limb lead misconnection, occurs frequently, and the adverse clinical consequences of this problem are becoming increasingly prominent.

[0003] Existing methods for identifying misconnections in limb leads on electrocardiograms (ECGs) still have significant diagnostic blind spots. For example, the sensitivity of the left upper limb (Left Arm, LA) / left lower limb (Left Leg, LL) leads is extremely low, and there is currently no unified diagnostic standard. Furthermore, most diagnostic criteria for ECG examinations are based on identifying misconnections in sinus rhythm or normal ECGs, and cannot identify misconnections in non-sinus rhythms (such as atrial fibrillation) or abnormal ECGs (such as right ventricular enlargement). The existing diagnostic mechanisms for ECG examinations are complex and difficult to understand, requiring memorization of multiple ECG misconnection pattern characteristics, which even most ECG specialists are not familiar with and can not master. In addition, existing methods for identifying misconnections in limb leads on ECGs do not comprehensively cover all diagnostic types of ECGs, such as ventricular pacing ECGs. Figure 1 Traditional methods for detecting lead misconnections have not been included in the research scope of such methods, resulting in incomplete coverage of traditional detection methods.

[0020] Figure 4 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0022] The following is combined Figure 1-Figure 4This invention describes a method, apparatus, and electronic device for detecting incorrect connections in electrocardiogram limb leads.

[0023] Figure 1 This is a flowchart illustrating the method for checking limb lead errors in electrocardiograms provided by the present invention, as shown below. Figure 1 As shown, the method for checking for incorrect connections in limb leads on an electrocardiogram includes steps S100 to S500, each step of which is detailed below.

[0024] S100: Obtain the first electrocardiogram showing the correct connection of limb leads during the test.

[0025] Obtain the subject's first electrocardiogram (ECG) from previous testing sessions. This first ECG has been verified in previous testing sessions and shows correct limb lead connections. The first ECG does not involve a neutral electrode.

[0026] S200: Obtain the second electrocardiogram of the subject during the current testing process.

[0027] Obtain a second electrocardiogram (ECG) of the same subject during the current testing process. The second ECG does not involve a neutral electrode.

[0028] S300: When it is determined that there are different QRS waveforms in the first and second electrocardiograms in limb leads, obtain the number of QRS waveform types generated by all pressurized unipolar leads in the first and second electrocardiograms.

[0029] The QRS complex in an electrocardiogram (ECG) represents the waveform of the ventricular depolarization process, consisting of three consecutive waves (Q wave, R wave, and S wave). The Q wave is a small downward wave. The R wave is the first upward wave after the Q wave. The S wave is the downward wave after the R wave.

[0030] Augmented monopolar leads are those that amplify signals from limb leads to enhance cardiac electrical activity in a specific direction. Augmented monopolar leads include the right arm Augmented Vector Right (aVR) lead, the left arm Augmented Vector Left (aVL) lead, and the left leg Augmented Vector Foot (aVF) lead.

[0031] When the first and second electrocardiograms show different QRS waveforms in the limb leads, it indicates one of the following three possible reasons: 1. Incorrect connection of the limb leads on the electrocardiogram; 2. Cardiac disease in the examiner; 3. The electrocardiogram operator performed the wrong examination on the wrong patient. In this case, to determine the cause, it is necessary to rule out the possibility of incorrect connection of the limb leads on the second electrocardiogram.

[0032] Count the types of QRS waveforms generated by the compressed unipolar leads in the first electrocardiogram (ECG). Count the types of QRS waveforms generated by the compressed unipolar leads in the second ECG. Compare the types of QRS waveforms generated by the compressed unipolar leads in the first ECG and the second ECG, and count the total number of QRS waveform types generated by all compressed unipolar leads in both ECGs.

[0033] S400: When the number of QRS waveform types is 3, the second ECG is determined to be an ECG with incorrect limb lead connections.

[0034] like Figure 1 As shown, when the number of QRS waveform types is 3, it indicates that there is a limb lead misconnection in the second electrocardiogram, thus confirming that the second electrocardiogram is an electrocardiogram with an incorrect limb lead connection.

[0035] S500: When the number of QRS waveform types is greater than 3, the second ECG can rule out the possibility of incorrect limb lead connections.

[0036] like Figure 2 As shown, when the number of QRS waveform types is greater than 3 (if the number of QRS waveform types is not 3), it indicates that there is no incorrect connection of limb leads or incorrect patient in the second electrocardiogram.

[0037] The method for checking limb lead errors in electrocardiograms (ECGs) provided in this invention involves acquiring a first ECG showing correct limb lead connections in a historical testing process; acquiring a second ECG in the current testing process; when different QRS waveforms for limb leads are found in the first and second ECGs, the number of QRS waveform types generated by all compressed unipolar leads in both ECGs is obtained; when the number of QRS waveform types is 3, the second ECG is determined to be an ECG with incorrect limb lead connections; when the number of QRS waveform types is greater than 3, the second ECG is determined to exclude cases of incorrect limb lead connections. This invention determines whether a second ECG is an ECG with incorrect limb lead connections by comparing the number of QRS waveform types in the second ECG and the first ECG with correct limb lead connections, thus achieving automatic ECG checking and improving the efficiency of ECG examination.

[0038] Based on the above embodiments, when the number of QRS waveform types is 3, after determining that the second electrocardiogram is an electrocardiogram with incorrect limb lead connections, the following steps are also included: Compare the QRS waveforms of the right arm unipolar aVR lead, the left arm unipolar aVL lead, and the left leg unipolar aVF lead of the second electrocardiogram, as well as the QRS waveforms of the aVR lead, aVL lead, and aVF lead of the first electrocardiogram, and obtain the comparison results. Based on the comparison results, the type of misconnected leads in the second electrocardiogram was determined.

[0039] like Figure 2 As shown, compare the QRS waveforms on the first and second electrocardiograms in the aVR lead. The aVR lead of the second electrocardiogram... 错 The QRS waveform of the second electrocardiogram and the aVL lead of the second electrocardiogram (aVL) 错 The QRS waveform of the second electrocardiogram and the aVF lead of the second electrocardiogram (aVF) 错 The QRS waveforms of the first electrocardiogram (aVR lead) are arranged vertically in the left column. 正 The QRS waveform and the aVL lead of the first electrocardiogram (aVL) 正 The QRS waveform and the aVF lead of the first electrocardiogram (aVF) 正 The QRS waveforms are arranged vertically in the right column.

[0040] Compare the QRS waveform of the first ECG in the left column with the QRS waveform of the second ECG in the right column, and determine the type of misconnected lead in the second ECG based on the comparison results.

[0041] This invention identifies the type of misconnected leads in the second electrocardiogram (ECG) by comparing the QRS waveforms of lead aVR, lead aVL, and lead aVF in the first and second ECGs. This improves the accuracy of determining the misconnected leads in the second ECG and facilitates subsequent adjustments to the ECG acquisition system based directly on the type of misconnected leads.

[0042] Based on the above embodiments, the type of misconnected leads in the second electrocardiogram is determined based on the comparison results, including: when the comparison results show that the QRS waveform of lead aVR in the second electrocardiogram is the same as the QRS waveform of lead aVL in the first electrocardiogram, the QRS waveform of lead aVL in the second electrocardiogram is the same as the QRS waveform of lead aVR in the first electrocardiogram, and the QRS waveform of lead aVF in the second electrocardiogram is the same as the QRS waveform of lead aVF in the first electrocardiogram, the type of misconnected leads is determined to be left and right hand reverse connection.

[0043] like Figure 2 As shown, when the comparison result is the aVR lead of the second electrocardiogram (aVR... 错The QRS waveform and the aVL lead of the first electrocardiogram (aVL) 正 The QRS waveform is the same as that of the second ECG aVL lead (aVL). 错 The QRS waveform and the aVR lead of the first electrocardiogram (aVR) 正 The QRS waveforms of the two ECG leads are the same, and the aVF lead of the second ECG (aVF) 错 The QRS waveform and the aVF lead of the first electrocardiogram (aVF) 正 If the QRS waveforms of the two leads are identical, it indicates that the aVF lead of the second ECG is correct, and the aVR and aVL leads of the second ECG are reversed. In this case, it can be determined that the incorrect lead connection type of the second ECG is left-right hand reversed connection.

[0044] This invention identifies the left and right arm reversal in the second electrocardiogram by comparing the QRS waveforms in lead aVR, lead aVL, and lead aVF of the first and second electrocardiograms. This facilitates subsequent adjustments to the electrocardiogram acquisition system based on the left and right arm reversal, thus improving the efficiency of adjusting the electrocardiogram acquisition system.

[0045] Based on the above embodiments, the type of misconnected leads in the second electrocardiogram is determined based on the comparison results, including: when the comparison results show that the QRS waveform of lead aVR in the second electrocardiogram is the same as the QRS waveform of lead aVR in the first electrocardiogram, the QRS waveform of lead aVL in the second electrocardiogram is the same as the QRS waveform of lead aVF in the first electrocardiogram, and the QRS waveform of lead aVF in the second electrocardiogram is the same as the QRS waveform of lead aVL in the first electrocardiogram, the type of misconnected leads is determined to be left limb reverse connection.

[0046] like Figure 2 As shown, when the comparison result is the aVR lead of the second electrocardiogram (aVR... 错 The QRS waveform and the aVR lead of the first electrocardiogram (aVR) 正 The QRS waveform is the same as that of the second ECG aVL lead (aVL). 错 The QRS waveform and the aVF lead of the first electrocardiogram (aVF) 正 The QRS waveforms of the two ECG leads are the same, and the aVF lead of the second ECG (aVF) 错 The QRS waveform and the aVL lead of the first electrocardiogram (aVL) 正 If the QRS waveforms of the two leads are identical, it indicates that lead aVR of the second ECG is correct, and leads aVL and aVF of the second ECG are reversed. In this case, it can be determined that the type of incorrect lead connection in the second ECG is left limb reversed connection.

[0047] This invention identifies the left limb reversal in the second electrocardiogram by comparing the QRS waveforms in lead aVR, lead aVL, and lead aVF of the first and second electrocardiograms. This facilitates subsequent adjustments to the electrocardiogram acquisition system based on the left limb reversal, thus improving the efficiency of adjusting the electrocardiogram acquisition system.

[0048] Based on the above embodiments, the type of misconnected leads in the second electrocardiogram is determined based on the comparison results, including: when the comparison results show that the QRS waveform of lead aVR in the second electrocardiogram is the same as the QRS waveform of lead aVF in the first electrocardiogram, the QRS waveform of lead aVL in the second electrocardiogram is the same as the QRS waveform of lead aVL in the first electrocardiogram, and the QRS waveform of lead aVF in the second electrocardiogram is the same as the QRS waveform of lead aVR in the first electrocardiogram, the type of misconnected leads is determined to be right limb reverse connection.

[0049] like Figure 2 As shown, when the comparison result is the aVR lead of the second electrocardiogram (aVR... 错 The QRS waveform and the aVF lead of the first electrocardiogram (aVF) 正 The QRS waveform is the same as that of the second ECG aVL lead (aVL). 错 The QRS waveform and the aVL lead of the first electrocardiogram (aVL) 正 The QRS waveforms of the two ECG leads are the same, and the aVF lead of the second ECG (aVF) 错 The QRS waveform and the aVR lead of the first electrocardiogram (aVR) 正 If the QRS waveforms of the two leads are identical, it indicates that the aVL lead of the second ECG is correct, and the aVR and aVF leads of the second ECG are reversed. In this case, it can be determined that the type of incorrect lead connection in the second ECG is right-sided limb reversal.

[0050] This invention identifies right-sided limb reversal in the second electrocardiogram by comparing the QRS waveforms in lead aVR, lead aVL, and lead aVF of the first and second electrocardiograms. This facilitates subsequent adjustments to the electrocardiogram acquisition system based on the right-sided limb reversal, thus improving the efficiency of adjusting the electrocardiogram acquisition system.

[0051] Based on the above embodiments, the type of misconnected lead in the second electrocardiogram is determined based on the comparison results, including: when the comparison results show that the QRS waveform of lead aVR in the second electrocardiogram is the same as the QRS waveform of lead aVL in the first electrocardiogram, the QRS waveform of lead aVL in the second electrocardiogram is the same as the QRS waveform of lead aVF in the first electrocardiogram, and the QRS waveform of lead aVF in the second electrocardiogram is the same as the QRS waveform of lead aVR in the first electrocardiogram, the type of misconnected lead is determined to be clockwise reverse connection.

[0052] like Figure 2 As shown, when the comparison result is the aVR lead of the second electrocardiogram (aVR... 错 The QRS waveform and the aVL lead of the first electrocardiogram (aVL) 正 The QRS waveform is the same as that of the second ECG aVL lead (aVL). 错 The QRS waveform and the aVF lead of the first electrocardiogram (aVF) 正 The QRS waveforms of the two ECG leads are the same, and the aVF lead of the second ECG (aVF) 错 The QRS waveform and the aVR lead of the first electrocardiogram (aVR) 正 If the QRS waveforms of the two ECGs are the same, it indicates that the aVR, aVL, and aVF leads of the second ECG are all connected incorrectly and are reversed in a clockwise direction.

[0053] This invention identifies the clockwise reverse connection of the second electrocardiogram by comparing the QRS waveforms of lead aVR, lead aVL, and lead aVF of the first and second electrocardiograms. This facilitates subsequent adjustments to the electrocardiogram acquisition system based on the clockwise reverse connection, thereby improving the efficiency of adjusting the electrocardiogram acquisition system.

[0054] Based on the above embodiments, the type of misconnected leads in the second electrocardiogram is determined based on the comparison results, including: when the comparison results show that the QRS waveform of lead aVR in the second electrocardiogram is the same as the QRS waveform of lead aVF in the first electrocardiogram, the QRS waveform of lead aVL in the second electrocardiogram is the same as the QRS waveform of lead aVR in the first electrocardiogram, and the QRS waveform of lead aVF in the second electrocardiogram is the same as the QRS waveform of lead aVL in the first electrocardiogram, the type of misconnected leads is determined to be counterclockwise reverse connection.

[0055] like Figure 2 As shown, when the comparison result is the aVR lead of the second electrocardiogram (aVR... 错 The QRS waveform and the aVF lead of the first electrocardiogram (aVF) 正 The QRS waveform is the same as that of the second ECG aVL lead (aVL). 错 The QRS waveform and the aVR lead of the first electrocardiogram (aVR) 正 The QRS waveforms of the two ECG leads are the same, and the aVF lead of the second ECG (aVF) 错 The QRS waveform and the aVL lead of the first electrocardiogram (aVL) 正 If the QRS waveforms of the two ECGs are the same, it indicates that the aVR, aVL, and aVF leads of the second ECG are all connected incorrectly and are reversed in a counterclockwise direction.

This facilitates subsequent direct adjustment of the electrocardiogram acquisition system based on the counterclockwise reverse connection, thereby improving the efficiency of adjusting the electrocardiogram acquisition system.

[0057] The following describes the device for detecting incorrect connections in electrocardiogram (ECG) limb leads provided by the present invention. The ECG limb lead detection device described below can be referred to in correspondence with the ECG lead detection method described above.
