Description
Technical field
The present invention relates to medical treatment ＆ health and artificial intelligence field, specifically, is related to a kind of automatic error-correcting electrocardiogram system
And method.
Background technology
Electrocardiogram (ECG or EKG) is to utilize electricity caused by electrocardiograph from body surface record heart each cardiac cycle
The technology of activity change figure.Electrocardiogram is one of clinical the most frequently used inspection, is widely used, and application includes but unlimited
In：1. record the electrical activity of human body normal heart；2. assisted diagnosis arrhythmia cordis；3. assisted diagnosis myocardial ischemia, myocardial infarction,
Judge the position of myocardial infarction；4. Diagnosing Cardiac expands, is plump；5. judge the influence of medicine or electrolyte situation to heart；6.
Judge cardiac pacing situation.
In conventional electrocardiographic examination, cardiac diagnosis lead-line component will be used, the electrode of cardiac diagnosis lead-line component is placed on people
Body different parts, to record and react the electrical activity of heart.6 chests of 4 limb leads electrodes and V1~V6 are generally laid to lead
Join electrode, record 12 lead electrocardiogram, be i.e. conventional cardiac diagnosis lead-line component shares 10 electrodes (Fig. 1), wherein 4 electrodes are
Limb electrode (is clamped on skin) frequently with clip, and conducting wire is black, and mark color is respectively red, yellow, green, black；Other 6
Individual is chest electrode (frequently with ball absorption is inhaled on skin), and conducting wire is white, and mark color is respectively red, yellow, green, brown,
It is black, purple, numbering V1, V2, V3, V4, V5, V6.Either limb electrode or chest electrode, require color and position one by one
It is corresponding.Fig. 2 is limb electrode installation site schematic diagram, and right upper extremity is red conducting wire, and left upper extremity is yellow conducting wire, left lower extremity
It is green conducting wire, right lower extremity is black conducting wire.Fig. 3 is chest electrode installation site schematic diagram, V1 leads：Right border of sternum
4 intercostals, V2 leads：The intercostal of left border of sternum the 4th, V3 leads：V2 and V4 lines midpoint, V4 leads：Left mid-clavicular line and the 5th rib
Between locate, V5 leads：At left anterior axillary line and V4 same levels, V6 leads：At midaxillary line and V4 same levels.
Because the position of electrode is distinguished according to colour code, electrode position mistake often occurs in actual use
Situation.Such as the V1 of chest leads, V2, V3, V4, V5, V6 positional faults (the factorial i.e. 720 kind combination that may have 6), or limbs
Lead positional fault (may have 4 factorial i.e. 24 kind combination, most commonly right-hand man is reversed).And electrode position mistake is often
Electrocardiogram metamorphosis can be caused, doctor deviation is occurred to electrocardiographic diagnosis, causes the diagnosis of mistake.In brief,
Current ECG lead systems conducting wire mark and position are one-to-one, are locked together.
Patent document CN106889985A, publication date 2017.06.27, disclose a kind of electrocardiogram limb lead module with

Electrocardiosignal is stated to transfer out；The electrode lead part include four limb leads lines and with the conducting wire is corresponding respectively connects
Four electrodes connect；Four limb leads lines are connected with the record with transport module, respectively from the edge of the box body
Draw.The 12 lead electrocardiogram acquisition includes described limb leads module with Transmission system and chest electrocardiographic lead positions
Band, the chest electrocardiographic lead positioning belt include flexible wearing portion and electrocardiograph lead device, and the electrocardiograph lead device is set
It is placed on the flexible wearing portion, wherein, the electrocardiograph lead device includes six electrodes corresponding to six precordial leadses
(V1-V6), six cardiac diagnosis lead-lines and lead interface, six electrodes (V1-V6) respectively with six cardiac diagnosis lead-lines
It is connected, six cardiac diagnosis lead-lines are connected with six connection terminals of the lead interface；The institute of the limb leads module
State lead connector and the lead interface on the chest electrocardiographic lead positioning belt is detachably connected.The chest heart
Electrograph lead positioning belt is provided with positioning datum mark, and the positioning datum mark includes position baseline and anchor point, described
Position baseline is straight line, and by the center of the electrode (V1) and electrode (V2), the anchor point is the electrode
(V1) and the line of centres of electrode (V2) midpoint.The invention advantage is accurately determine ECG electrode position, can be same
When detect the heart before and limbs electrocardiosignal, it is convenient to the signal detected is transferred to terminal, can be quickly right in real time
Human body electrocardio is diagnosed, and is dressed suitable for ordinary populace in non-Waiting time.
However, 12 lead electrocardiogram acquisition disclosed in above-mentioned patent document is only applicable to people outside hospital with Transmission system
Voluntarily ECG detecting, by being equipped with electrocardiographic lead positioning belt in chest, position baseline and positioning are noted in positioning belt subscript
The mode of point prevents electrode position mistake, and the system is not particularly suited for Electrocardioscopy professional in institute, and it corrects electrode position
The means of mistake are not suitable for clinic yet.
To sum up, need badly a kind of inspection suitable for electrocardiogram and correct electrode placement positions mistake, to ensure just to make a definite diagnosis
Disconnected method, but relevant report is had no at present.
