Description
[invention field]
The present invention relates to a kind of electron medical treatment checkout gear, especially a kind of ECG tester.
[background of invention]
Existing ECG tester all is to design according to routine 12 lead electrocardiogram detection methods of standard a century, analog electrocardiogram figure instrument is arranged, form (as 6511 type electrocardiographs) by ecg amplifier, pen recorder,, lead cable and corresponding connection ground electrode thereof; The digitized electrocardiograph is arranged, form by ecg amplifier, sampling plate, micro computer, hot array recorder, lead cable and corresponding connection electrode and 1 ground electrode thereof.The latter divides for again by the portable electrocardiograph of the intelligent control of single-chip microcomputer with by the intelligent desk-top electrocardiograph two big classes of controlling of PC, often has other auxiliary device (as display, printer etc.).
Conventional 12 lead systems comprise limb lead (being standard lead I, II, III and augmented limb lead aVR, aVL, aVF) and chest lead V
1～V
6This method be at human body left hand, the right hand, left foot, respectively get a sampled point, get 6 sampled points at left chest, corresponding each sampled point of checkout gear is provided with a test electrode, i.e. nine test electrodes altogether.Therefore, the existing cable that leads all is to adopt the 10 cores cable that leads, and wherein a heart yearn is connected with a ground electrode, and all the other nine heart yearns and above-mentioned nine corresponding connections of test electrode.When the thought-read electrograph, near 6 sampled points that six test electrodes are corresponding and the left breast of human body is contact, all the other 3 test electrode L, R, F correspondence contact with left hand and right hand, 3 sampled points of left foot, and ground electrode contacts with right crus of diaphragm, so, obtain following 12 road electrocardiograms (data) according to " test value=[(positive input terminal is with respect to the potential difference values of ground electrode)-(negative input end is with respect to the potential difference values of ground electrode)] * amplification coefficient ":
I: with the left hand sampled point is positive input terminal, and right hand sampled point is a negative input end;
II: with the left foot sampled point is positive input terminal, and right hand sampled point is a negative input end;
III: with the left foot sampled point is positive input terminal, and the left hand sampled point is a negative input end;
AVR: with right hand sampled point is positive input terminal, and left hand, left foot sampled point are negative input end jointly;
AVL: with the left hand sampled point is positive input terminal, and the right hand, left foot sampled point are negative input end jointly;
AVF: with the left foot sampled point is positive input terminal, and the right hand, left hand sampled point are negative input end jointly;
V
1～V
6: 6 sampled points of chest positive input terminal of respectively doing for oneself, the right hand, left hand, 3 sampled points of left foot are negative input end jointly.
Above-mentioned 12 road electrocardiograms become one group of waveform (data), medically promptly are according to these Electrocardiographic waveforms and standard cardioelectric figure waveform relatively, and these electrocardiographic waves itself compare each other, come human body is done diagnosis.
Above-mentioned negative input end is called as reference potential with respect to the potential difference values of ground electrode, and obviously it is to the one-tenth figure important influence of electrocardiographic wave.Because above-mentioned 12 road electrocardiograms are when becoming figure, its reference potential value disunity, therefore, when the reference potential value is different, the influence that each lead electrocardiogram waveform is formed positive wave and negative wave also has nothing in common with each other, therefore, the true looks that more often are difficult to reflect objective fact between this 12 road electrocardiographic wave.
In view of above-mentioned reference is to differ, cause the reference potential disunity, and then cause formed each Electrocardiographic waveform to lose unified basis relatively, the applicant once proposed the notion of head chest lead system.12 road electrocardiograms of every cover head chest lead have 13 sampling positions (promptly getting breast, the back of the body, waist, 12 sampled points of abdominal part and 1 sampled point of the right front volume of head each time).When the head chest lead system realizes that record is led in the left side, its corresponding transmission HV

3Signal, and to get the right front volume sampled point of head jointly be that reference is to come recording ecg, meet modern experiment and learn " reference is a uniqueness " principle, can solve above-mentioned reference is the problem that disunity brings, but this notion does not still have specific embodiment, does not study as yet both at home and abroad and adopts this ECG tester that leads.
Secondly, conventional 12 another drawbacks of leading are, the field strength distribution of its each negative input end (being made up of with multi-form the right hand, left hand, left foot) cardioelectric field shows, left foot place electromotive force is very high, the also polarization of left hand electromotive force causes that the value of the reference potential that majority leads is often bigger than normal (to comprise I, III, aVR, aVL, aVF and V
1～V

3R～V
8R), the one-tenth figure to electrocardiographic wave has a significant impact like this.If because positive input terminal with respect to the difference of the potential difference values of ground electrode and reference potential on the occasion of, one-tenth figure promptly is reflected as positive wave, if this difference negative value, one-tenth figure promptly is reflected as negative wave.In order to reflect the objective reality situation of positive input terminal signal as far as possible, promptly truly reflect the waveform of positive input terminal with respect to the potential difference values formation of ground electrode, just should make the size of reference potential the smaller the better with variation.
Moreover each reference point and earth point are far apart, and electrical activity between the two is difficult to harmonious, also are unfavorable for the correct expression of positive input terminal signal.
There is above-mentioned drawback just because of the conventional leads system always, therefore, though clinical electrocardiography experiences century-old several generations's research, but even to this day, it still is in experience subject level, still can't solve the following many disadvantages of bringing because of above-mentioned drawback, promptly blind area, right ventricle, difficulty are distinguished P ripple, false change, the location is inaccurate and standard is floated.Just because of this, the electrocardiogram that records of all clinical electrocardiographs has only 60～70% to the correct diagnosis of myocardial infarction both at home and abroad, to the loose diagnosis in right ventricle and clinical coincidence rate only about 30%.
[summary of the invention]
Main purpose of the present invention is to provide a kind of ECG tester that can effectively improve the correct diagnosis of electrocardiogram.
The objective of the invention is to be achieved through the following technical solutions: this ECG tester comprises network board at least, amplifier, analog-digital converter, computer, display, cable and electrode lead, be laid with the analog signal transmission circuit on this network board and divide line circuit, and for leading cable, some connectivity ports that amplifier and network board electrically connect, wherein, this cable that leads comprises conventional leads heart yearn that transmits one group of conventional leads ECG signal and the head chest lead heart yearn that transmits the head chest lead ECG signal, and described conventional leads heart yearn comprises 3 limbs signal (R, L, F) heart yearn, 6 chest lead signals (V
