Define a linear function formula 2:
Z=T0+T1*f1+T2*f2+T3*f3
The related coefficient f1, f2 and f3 that each group of calculating obtains are substituted into formula 2 and obtain a corresponding function Z, it will
Each function Z substitutes into a decision formula 3:
The decision function g (Z) corresponding to correct electrocardiogram (ECG) data is equal to 1 and is determined, solution formula 3 will be counted by formula 3
It calculates each of acquisition function Z and substitutes into formula 2, calculate the T coefficient matrix numerical value obtained in formula 2:
T=[T0T1T2T3]；
Step 5: using ECG detecting equipment official testing electrocardiogram (ECG) data same in step 2, the same institute for using step 1
State simplified electrode position judgment step, obtain a plurality of official testing electrocardiogram (ECG) data of multiple time serieses first lead,
Formal electrocardio test voltage CV1, CV2 and the CV3 of second lead and third lead；
The formal electrocardio test voltage of a plurality of official testing electrocardiogram (ECG) data for multiple time serieses that test is obtained
The matrix numerical value that the coefficient bk of acquisition is calculated in CV1, CV2 and CV3 and step 3 substitutes into the formula 1, each time
Sequence is corresponding to obtain one group of virtually formal voltage DV1, DV2 and DV3；
Calculate corresponding virtual formal of formal electrocardio test voltage CV1, CV2 and CV3 described in one group of each time series
Voltage DV1, related coefficient f1, f2 and f3 between DV2 and DV3；By calculate obtain the related coefficient f1, f2 and f3 with
And step 4 calculates the T coefficient matrix numerical value obtained and substitutes into the numerical value that formula 2 obtains linear function Z, by the function Z's
Numerical value substitutes into decision formula 3, calculates the numerical value for obtaining the decision function g (Z)；
If the numerical value for calculating the decision function g (Z) obtained is more than or equal to the calibration numerical value t of a setting, electrode is judged
Position does not have wrong；
If the numerical value for calculating the decision function g (Z) obtained is less than the calibration numerical value t, electrode position wrong is judged simultaneously
Sending reports an error prompting, repeats step 5, until judging that electrode position does not have wrong.
