For example, the condition for determining the Minnesota code 1-1-2 may be Q duration ≥ 0.04 second and Q / R ratio <1/3. Referring to FIG. 4, the duration of Q is 0.042 s, and the Q / R ratio is 180/1220 as the ratio of the Q wave amplitude and the R wave amplitude. Therefore, FIG. 4 satisfies the Q duration (0.042 s) ≥ 0.04 second, the Q / R ratio (180/1220) <1/3, which is a condition for determining the Minnesota code 1-1-2. If it appears, the code determination unit 320 may determine the Minnesota code 1-1-2.

For example, the condition for determining the Minnesota code 1-2-3 may be the presence or absence of a QS pattern. If the value of the QS pattern is 1, it is a QS pattern, and if the value of the QS pattern is 0, it may represent that it is not a QS pattern. Referring to FIG. 5, since the value of the QS pattern represents 1, FIG. 5 may be Minnesota code 1-2-3. Accordingly, when the ECG signal of FIG. 5 is shown, the code determiner 320 may determine the Minnesota code 1-2-3.

6 is a flowchart illustrating a method for determining a Minnesota code according to an embodiment of the present application, and FIG. 7 is a diagram illustrating an example of Minnesota code determination according to an embodiment of the present application.

For example, the Minnesota code 8-3-1 can recognize arrhythmias-atrial fibrillation. Referring to FIG. 6, the code determiner 320 may determine an arrhythmia-atrial negative rhythm through the algorithm shown in FIG. 6 in the measured ECG signal. In addition, when the ECG signal shown in FIG. 7 is displayed, the code determiner 320 may determine the Minnesota code 8-3-1.

Also, as an example, the code determiner 320 may determine the MN code using at least one of a plurality of feature parameters, a first feature parameter, a second feature parameter, a third feature parameter, and a fourth feature parameter. The first feature parameter, the second feature parameter, the third feature parameter and the fourth feature parameter may be calculated in a time interval that occurs every two seconds regardless of the R peak of the ECG. For example, the first two seconds appearing in the ECG signal may be referred to as a first time interval, and the second second interval after the first time interval may be referred to as a second time interval.

The first feature parameter may be a ratio of the maximum value and the minimum value of the ECG signal in the time interval. The first feature parameter may have a plurality of first feature parameters in a plurality of time intervals.

The first feature parameter may be expressed as Equation 2 below.

[Equation 2]

In this case, max (sx (n)) represents the maximum value of the ECG signal in the time interval, and abs (min (sx (n)) represents the absolute value of the minimum value of the ECG signal in the time interval.

The second characteristic parameter is a point in time at which the ECG signal changes from a positive value (+) to a negative value (-) or in a time point when the ECG signal changes from a negative value (-) to a positive value (+), that is, It may be the number of time points at which the graph passes zero. The second feature parameter may have a plurality of second feature parameters in a plurality of time intervals.

The third feature parameter may be a difference between the number of negative waves in the time interval and the number of negative waves in the previous time interval. Here, negative waves mean when the ECG signal is less than zero. In other words, the third feature parameter may be a difference between the number of negative waves in the first time interval and the number of negative waves in the second time interval. In addition, the third feature parameter may have a plurality of third feature parameters in a plurality of time intervals.

The fourth feature parameter may be a ratio between the area of the positive wave and the area of the negative wave in the time interval. The fourth feature parameter may have a plurality of fourth feature parameters in a plurality of time intervals.

The fourth feature parameter may be expressed as Equation 3 below.

[Equation 3]

In this case, S1 denotes an area when the ECG signal in the time interval is greater than zero, and S2 denotes an area when the ECG signal in the time interval is smaller than zero.

8 is a schematic flowchart of a process of determining a Minnesota code and determining arrhythmia information according to an embodiment of the present application.

The Minnesota code output device 1 may include an arrhythmia information determiner 20.

Referring to FIG. 8, the diagnostic parameter extracting unit 200 may extract a plurality of diagnostic parameters based on the R peak extracted by the R peak extracting unit 10, and the analysis index determination unit 310 may include the plurality of diagnostic parameters.

At least one of T wave duration, QRS peak size, QRS duration, PR interval, PQ interval, SQ interval, QT interval, PR interval, QTc, heart rate and ST value, and Q wave object as an ECG indicator ), QS patterns, High Amplitude R wave, ST Junction, ST Depression, ST Segment, and ST Elevation Arrhythmia information may be determined using the T-wave object index, AV Conductivity index, Ventricular Conductions index, Arrhythmias index, and at least one Minnesota code determined by the Minnesota code determiner 300. have. In addition, the arrhythmia information determiner 20 may determine arrhythmia information using at least one of the plurality of feature parameters.

9 is a diagram illustrating a plurality of feature parameters according to an embodiment of the present application.

9 (a) shows a graph of ventricular fibrillation, FIG. 9 (b) shows a graph of the first feature parameter, and FIG. 9 (c) shows a graph of the second feature parameter. 9 (d) shows a graph of the third feature parameter, and FIG. 9 (e) shows a graph of the fourth feature parameter.

For example, ventricular fibrillation, which is a type of arrhythmia, may be detected through a tree structure classification algorithm using the first feature parameter, the second feature parameter, the third feature parameter, and the fourth feature parameter. The arrhythmia information determiner 20 may determine ventricular fibrillation when all of the conditions of the first feature parameter> 6000, the second feature parameter> 0, the third feature parameter> 0, and the fourth feature parameter> 5000 are satisfied.

In addition, since the arrhythmia information determiner 20 divides the ventricular fibrillation (VF) into a rhythm, all of the conditions of the first feature parameter, the second feature parameter, the third feature parameter, and the fourth feature parameter do not satisfy the ventricular fibrillation. Even if it is determined that the cardiopulmonary fibrillation is not determined as a result of abnormality of the electrocardiogram, the output of the ventricular fibrillation may be finally output. Therefore, the rhythm divided by the final output rhythm and the feature parameter condition may be different. For example, the arrhythmia information determiner 20 is determined to be VF-VF-VF-nonVF-nonVF-nonVF-nonVF under the condition of four feature parameters, but the final result is VF-VF-VF-VF-nonVF-nonVF can be output as -nonVF In this way, errors that are incorrectly judged as VF as nonVF and nonVF as VF can be minimized. For example, the arrhythmia information determiner 20 may correct VF-VF-VF-VF-VF-VF-VF even if an error occurs in the middle with VF-VF-VF-nonVF-VF-VF-VF. have.

The output unit 400 may output the determined at least one Minnesota code.

For example, the output unit 400 may be, but is not limited to, a TV device, a computer, or a portable terminal through which a remote user can access a server through a network. The output unit 400 may output the Minnesota code determined by the Minnesota code determination unit 300.

At least one or more of the arrhythmia information determined in the) may be output.

For example, the output unit 400 may output the cardiac disease related information and the abnormal ECG signal information determined by the arrhythmia information determiner 20 through a screen.

The Minnesota code output device 1 may include a communication unit. The communication unit may transmit at least one Minnesota code to an external device through a communication channel.

Also, for example, the communication unit may include a wireless communication module. The communication unit may transmit abnormal ECG signal information to an external device by performing wireless communication. For example, the external device may be, but is not limited to, a TV device, a computer, or a portable terminal through which a remote user can access a server through a network.

Professional ECG diagnostic codes such as multiple diagnostic parameters, ECG indicators, multiple Minnesota codes, and arrhythmia information can be checked through external devices in real time, allowing users to read ECG signals for a long time without the need for expert intervention or a separate diagnostic program. Patients with high-risk cardiac disease, as well as patients with hepatic arrhythmia, can receive early detection of ECG signals and receive real-time analysis information, enabling early detection of cardiac disease, and treating cardiac diseases quickly and effectively.
