Description

[0001] The present invention relates to an integrated multi-electrode for 12-channel ECG measurement and a 12-channel ECG detection method using the same,

An electrocardiogram (ECG) is detected by applying an integral multi-electrode to a 12-lead electrocardiogram detection method, wherein an electrocardiogram (ECG) is detected in each of the sub- A 12-channel electrocardiogram signal can be detected more accurately by detecting an electrocardiogram signal that is more suitable for the 12-lead electrode position in the signal using the S peak and applying it as a signal detected at the 12-lead electrode position, The present invention relates to an integrated multi-electrode for electrocardiogram measurement and a 12-channel electrocardiogram detection method using the same.

The electrocardiogram detects electrical activity due to mechanical activity of the heart, such as contraction or expansion of the heart, amplified and recorded in a graph. The electrocardiogram includes P, Q, R, S and T as shown in FIG.

The 12-channel electrocardiogram is measured by attaching 10 electrodes to the patient's body as shown in FIG. Six of the 10 electrodes (V1 to V6) are attached to a landmark in a given anatomy according to the unipolar thoracic induction method, and the remaining four electrodes are attached to the patient's limbs: left hand and foot, right hand and foot, respectively Respectively. Electrodes respectively attached to the left hand and foot, and the right hand and foot, respectively, may be attached to the left, right and bottom sides of the upper part of the chest, as the case may be.

Accurately and periodically measuring electrocardiograms for arrhythmia, etc., is important to accurately position the chest electrodes. However, since it is difficult to arrange and attach a plurality of electrodes at precise positions, time can be consumed, and medical knowledge and skills are required for the person who attaches the electrodes. Thereby, there is a high possibility that the electrode is not appropriately placed on the anatomical landmark, and the wrong chest electrocardiogram is obtained out of the correct position. Also, when measuring the periodical ECG, six heart electrodes are arranged at different positions, Accuracy and reliability can be reduced when managing ECGs.

As a conventional technique, Korean Patent Laid-Open No. 10-2005-0119890 discloses an integrated multi-electrode for measuring a bio-signal, a bio-signal measurement method and apparatus using the same, and a lead search method using the multi-electrode. The electrodes are arranged in a circle, and a reference electrode is provided at the center of the electrode. When the leads are selected at each electrode, the size of the R peak is compared to select the leads.

Since the multiple electrodes of Korean Patent Laid-Open Publication No. 10-2005-0119890 have a plurality of electrodes arranged in a circle, if the center portion is actually an accurate lead position, the multiple electrodes can detect a signal at the position of the correct lead none. Therefore, more densely placed multiple electrodes are desired.

In addition, in Japanese Unexamined Patent Application Publication No. 10-2005-0119890, the lead is selected by comparing the R peak of the electrocardiogram signal of the sub electrode in order to select the position of the correct lead among the signals detected in the multiple electrodes, It is not easy to select the lead on the basis of the magnitude of the change of the magnitude depending on the position of the six chest electrocardiogram electrodes (V1 to V6) upon detection of the 12-channel electrocardiogram. In addition, when the R wave is the largest signal of the electrocardiogram signal, if the gain of the amplifier is too large or too large, it may be difficult to compare the R peak difference between the electrocardiogram signals of the sub-electrodes in the multiple electrodes And therefore always requires an expert.

On the other hand, the S wave shows a relatively large change in the magnitude depending on the position of the six chest electrocardiogram electrodes (V1 to V6). When the 12-lead electrode position (i.e., lead) is set using the S wave, , 12-channel electrocardiogram can be measured quickly and accurately by non-expert.

Therefore, a two-channel electrocardiogram detection method for setting the 12-lead electrode position (i.e., lead) using S waves is desired.

That is, a method of detecting an electrocardiogram signal more suitable for the 12-lead electrode position among the electrocardiogram signals detected at the detailed electrode in the integral multi-electrode is required for the unskilled person to promptly and precisely measure the 12-channel electrocardiogram Is desired.

FIG. 3 is an integral multi-electrode for 12-channel electrocardiogram measurement according to an embodiment of the present invention, and FIG. 4 shows an example in which multiple electrodes of FIG. 2 are mounted for 12-channel electrocardiogram measurement.

The integral multiple electrode 10 has a plurality of detailed electrodes P1 to P8 on a sheet in the form of a gourd. The sheet is made of a PE-form, and a member of a detailed electrode made of silver chloride (Ag / AgCl) is attached to one side of the sheet, and a solid-type hydrogel hydrogel, and transparent PET is attached to the upper surface of the hydrogel above the detailed electrode.

4 (a) shows the positions of six chest electrocardiogram electrodes (V1 to V6) at the time of 12-channel electrocardiogram detection and FIG. 4 (b) And is mounted at the position of the chest electrocardiogram electrodes (V1 to V6).

As shown in FIG. 4 (a), the electrocardiogram should be accurately detected by attaching the electrocardiogram electrode to the landmark of a predetermined anatomy according to the unipolar thoracic induction method, but it is easy for the unskilled person to appropriately place the electrocardiogram electrode in the anatomical landmark not. In order to accurately detect the electrocardiogram even when the anatomical landmark is accurately located, the multiple electrodes having a plurality of detailed electrodes are used to detect an anatomical landmark, And automatically detects the nearest one.

FIG. 5 is a block diagram schematically illustrating a system for detecting a 12-channel electrocardiogram using multiple electrodes according to the present invention. FIG. 6 is a block diagram schematically illustrating a first multi-electrode unit and a first multi- An electrode unit 100, a preprocessing unit 200, an arithmetic processing unit 300, a display unit 350, and a memory unit 370.

The electrode unit 100 includes first to seventh multi-electrode units 110 to 160 mounted at the positions of the six chest electrocardiogram electrodes V1 to V6. The first multi-electrode unit 110 to the sixth multi-electrode unit 160 may be disposable electrodes.

6, the first to seventh multi-electrode units 110 to 160 may include first to eighth detailed electrodes 111 to 118, which are a plurality of detailed electrodes P1 to P8, ).

The preprocessing unit 200 preprocesses the electrocardiogram signal detected by the electrode unit 100, removes noise, and converts the electrocardiogram signal into a digital signal. 6, the first sub-electrode pre-processing unit 211 to the eighth sub-electrode pre-processing unit 218 are provided, and the first sub-electrode pre-processing unit 211 to the eighth sub-electrode pre- A filter unit and an A / D conversion unit, and preprocesses the electrocardiogram detected by the sub-electrodes 111 to 118 of the first to seventh multi-electrode units 110 to 160.

That is, electrocardiogram signals detected at the 12-lead electrode positions among the electrocardiograms detected by the sub-electrodes 111 to 118 of the first multi-electrode unit 110 to the sixth multi-electrode unit 160 are selected, 350, and stores it in the memory unit 370. [

FIG. 7 is a flowchart schematically illustrating a 12-channel electrocardiogram detection method using the integrated multi-electrode of the present invention, FIG. 8 shows an example of electrocardiogram waveforms detected at 6 sub-electrodes, FIG. Is an example of the electrocardiogram signal of the induction electrode set from the electrocardiogram of the subject.

7, the arithmetic processing unit 300 receives electrocardiogram signals of the sub-electrodes of the respective multi-electrode units 110 to 160 received from the preprocessing unit 200, The S peak of the electrocardiogram signals are compared and one of the detailed electrodes is selected as a corresponding induction electrode (i.e., corresponding lead) for each of the multiple electrode units 110 to 160, and the signal detected at the selected induction electrode is output .

In the R peak detection step, the arithmetic processing unit 300 receives the electrocardiogram signals of the respective sub-electrodes of each of the multiple electrode units from the preprocessing unit 200 and calculates an R-peak (R-Peak) (S110). In other words, a signal is received from six multiple electrodes attached to the chest, and an R peak is detected from the electrocardiogram signal of the detailed electrode of each of the multiple electrodes received.

In the S peak detecting step, an S peak (S-peak) is detected based on the R peak detected at each sub electrode (S120). That is, the minimum value appearing after the detected R peak is detected, and the minimum value is set as the S peak.

In the S peak absolute value detection step, the absolute value of the S peak detected at each sub-electrode is detected (S130).

In step S140, the absolute value of the S peak detected in each sub-electrode is sorted in order of magnitude and the second largest absolute value of the S peak is extracted from the S peak absolute value to the second largest value detection step.

In the induction electrode setting step, the detailed electrode having the second largest absolute value of the S peak is set as a corresponding induction electrode (S150).

That is, as shown in FIG. 8, if the S peak absolute value is listed and the second electrode having the second largest value is set as the induction electrode, the electrocardiogram of the induction electrode is detected as shown in FIG.

It is determined whether all six induction electrodes have been set (step S160). If the six induction electrodes are not yet set, the process returns to the R peak detection step.

If all six induction electrodes are set in the step of determining whether six induction electrodes are set, the electrocardiogram signals are received from the six induction electrodes and transmitted to the display unit 350 and the memory unit 370 (S170).

In FIG. 7, it is an algorithm for selecting only one signal that is the most suitable among electrocardiogram signals measured with multiple electrodes.

In general, 12-channel electrocardiogram can be measured with only 10 electrodes. Four signals can be placed on the limb electrode and six signals can be detected from the multiple electrodes using 6 electrodes placed on the chest electrode

The reason why the S peak is used as a reference in the present invention is that the order of each cycle is not changed in the case of measuring the electrocardiogram by the multiple electrodes and the linear change rate is changed for each electrode position.

10 (a) and 10 (b) illustrate a front surface of an integral multi-electrode, that is, a skin contact surface (that is, an electrode attachment surface) The rear surface of the electrode, that is, the connection surface of the lead connector.

10 (a) shows a detailed electrode made of silver chloride (Ag / AgCl) and an electrode adhering surface on which a hydrogel is placed. The distance between the electrodes is kept to the minimum possible length. The total size of the electrodes can be designed by limiting the width to the extent that they do not interfere with the electrode attachment points of the individual chest ECG electrodes.

11A to 11F are graphs comparing V1 to V6 at the time of 12-channel electrocardiogram detection when the multi-electrode of the present invention is used and when the specialist detects it by the conventional method.

11A is an example of detecting V1 when a 12-channel electrocardiogram is detected, FIG. 11B is an example of detecting V2 when a 12-channel ECG is detected, FIG. 11C is an example of detecting V3 when a 12- FIG. 11E is an example of detecting V5 when 12-channel electrocardiogram is detected, FIG. 11F is an example of detecting V6 when detecting 12-channel electrocardiogram, and FIG.

As shown in FIGS. 11A to 11F, it can be seen that similar results can be obtained when the multi-electrode of the present invention is used and when it is detected by the conventional method.

The present invention is configured to detect only one optimal electrocardiogram data among the data measured with the multiple electrodes of the present invention. The electrocardiographic waveform measured by chest induction electrode shows a large difference in the S peak value, and the most stable conduction state is observed in the S-peak value of the electrocardiogram measured by the chest induction electrode (ventricular depolarization (systolic period)), Since the waveforms of V6 do not change in order, they are used as a reference in the present invention.

In the present invention, a detailed electrode having a signal corresponding to a second signal in the order of the magnitude of the absolute value at the S-peak value is set as a corresponding induction electrode. To this end, the present inventors conducted a basic experiment and the results are shown in Table 1 .

In the basic experiment performed by the present inventors, a single electrode was attached to a point designated by a specialist from V1 to V6 in the same subject, and the electrocardiogram was measured (Data 1). The electrode of the present invention was attached to a portion including the same point, (Data 2), and the Correlation Coefficient of two signals according to the magnitude order of the absolute value was obtained from the S-peak value.

As shown in Table 1, it can be seen from the S-peak value of the electrocardiogram measured by the multi-electrode of the present invention that the signal corresponding to the second order in absolute value order has the greatest correlation coefficient with the reference signal there was..
