In other embodiments of the present application, the processor module 130 may further include a battery. The processor module 130 may further include a signal transmitter (not shown) for transmitting information.

Please refer to Figure 1 and Figure 2 of this case together. In one embodiment, the user contacts the first electrode component 110 of the electrocardiographic extraction device 100 with the first portion of the limb thereof, and when the second electrode component 120 of the electrocardiographic extraction device 100 contacts the second portion of the user's limb The processor module 130 can obtain the potential difference between the first part and the second part of the user's limb through the first electrode element 110 and the second electrode element 120, which is the first part and the second part of the user's limb 1-lead or single lead ECG information between the parts. Similarly, when the first electrode component 110 of the electrocardiographic extraction device 100 contacts the first portion of the user's limb and the second electrode component 120 contacts the third portion of the user's limb, the processor module 130 can be obtained The potential difference between the first portion and the third portion of the user's limb is another single-lead electrocardiogram information between the first and third portions of the user's limb. When the first electrode component 110 of the electrocardiographic extraction device 100 contacts the second portion of the user's limb and the second electrode component 120 contacts the third portion of the user's limb, the processor module 130 can obtain the user accordingly. The potential difference between the second and third portions of the limb is another single-lead electrocardiogram information between the second and third portions of the user's limb. When the first, second and third parts of the user's limb are the right upper limb (Right Arm, RA), the left upper limb (Left Arm, LA) and the left lower limb (Left Leg, LL), the three methods are obtained in the above three ways. The single-lead ECG information corresponds to the three limb leads in the 12-lead ECG (Lead I, Lead II, Lead III), and the above three limb leads will be detailed later.

According to the upper section, according to the three limbs in the twelve-lead ECG The calculation rule, wherein the value of Lead I is equal to the potential difference between LA and RA, the value of Lead II is equal to the potential difference between LL and RA, and the value of Lead III is equal to the potential difference between LL and LA, and the calculation formula is as follows.

Equation 1: Lead I = LA - RA .

Equation 2: Lead II = LL - RA .

Equation 3: Lead III = LL - LA .

As shown in the above formula 1, the value of Lead I is calculated as the result of subtracting the potential value of RA from the potential value of LA. In Equation 2 shown above, the value of Lead II is calculated as the result of subtracting the potential value of RA from the potential value of LL. In Equation 3 shown above, the value of Lead III is calculated as the result of subtracting the potential value of LA from the potential value of LL.

Therefore, when the processor module 130 obtains the potential difference between the first, second, and third portions of the user's limb, after the crossover operation, the first, second, and the first part of the user's limb can be obtained. The potential values of the three parts are the first to third potential values, respectively, and each represents the potential value of RA, LA, and LL.

The correspondence between them is reordered.

The upper section, because the first, second and third of the user's limbs Some of the first to third potential values (ie, RA, LA, LL) have been obtained after the operation. Therefore, the first to sixth representative of the user's chest can be inversely calculated according to the values of the fourth to ninth potential differences. Some of the respective potential values are V1', V2', V3', V4', V5' and V6'. According to the calculation rules of the other six chest leads (Lead V1, Lead V2, Lead V3, Lead V4, Lead V5, Lead V6) in the twelve-lead electrocardiogram, the calculation of each chest lead is represented by the user. The potential value of one of the first to sixth portions of the chest is subtracted from the average of the potentials of the first to third portions of the user's limb, and the calculation formula is as follows.

Equation 7: Lead V 1 = V 1 '-( LA + LL + RA )/3.

Equation 8: Lead V 2 = V 2'-( LA + LL + RA )/3.

Equation 9: Lead V 3 = V 3'-( LA + LL + RA )/3.

Equation 10: Lead V 4 = V 4'-( LA + LL + RA )/3.

Equation 11: Lead V 5 = V 5'-( LA + LL + RA )/3.

Equation 12: Lead V 6= V 6'-( LA + LL + RA )/3.

In Equation 7, as shown above, the value of Lead V1 is calculated by subtracting the average of the three potentials of LA, LL, and RA from the potential value of V1'. In Equation 8 shown above, the value of Lead V2 is calculated as the result of subtracting the average of the three potentials of LA, LL, and RA from the potential value of V2'. In Equation 9, as shown above, the value of Lead V3 is calculated by subtracting the average of the three potentials of LA, LL, and RA from the potential value of V3'. In Equation 10 shown above, the value of Lead V4 is calculated by subtracting the average of the three potentials of LA, LL, and RA from the potential value of V4'. As shown in the above formula 11, the value of Lead V5 is calculated by subtracting the average values of the three potentials of LA, LL, and RA from the potential value of V5'. Formula 12 shown above, the value of Lead V6 is calculated as V6' The result of subtracting the average of the three potentials of LA, LL, and RA from the potential value. The first to third potential values representing RA, LA, and LL have been obtained after the operation, and represent the first to sixth portions of the user's chest, V1', V2', V3', V4', V5', and V6. The 'equipotential value has also been obtained, and the calculation results of the six chest leads Lead V1 to Lead V6 can be obtained by calculation.
