Description
Technical field
The present invention relates to the technical fields of medical equipment, more particularly to a kind of feasible multi-lead ECG examination and electrocardio
The Intelligent bracelet of monitoring.
Background technique
Cardiovascular disease seriously endangers human health, has the characteristics that sudden, transience and risk when falling ill,
Such as angina pectoris attacks, paroxysmal arrhythmia cordis, cardiac origin of syncope breaking-out, usually diagnosis goldstandard is the electrocardio to break out at that time
Figure, needs when necessary and usually electrocardiogram compares.But due to angina pectoris, paroxysmal arrhythmia cordis, syncope sporadic and not
The features such as predictability, is often difficult to obtain the electrocardiogram of breaking-out at that time.Dynamic ECG for 24 hours is clinically mostly used at present
(holter) change of paroxysmal electrocardiogram myocardial ischemia, arrhythmia cordis etc. are captured, but to several days, a few weeks, even several years some months
Primary angina pectoris, paroxysmal arrhythmia cordis, syncope just occurs and still there is limitation.Although cardiac origin of syncope only accounts for fainting
The 15% of the cause of disease, however be the first cause that syncope leads to sudden death, immediate cause is mainly malignant ventricular arrhythmia, this
Require clear electrocardiographic diagnosis.The acute myocardial infarction AMI overwhelming majority can be come out by electrocardiographic diagnosis, and be required as early as possible
Row ECG examination.But many patients think little of due to that can look into the local too far or patient of electrocardiogram from hospital, clinic etc.
Without timely row ECG examination.If patient can carry blood glucose meter as diabetic and carry out Blood sugar self-measure
(SMBG) it carries electrocardiograph equally to have an electro-cardiogram whenever and wherever possible and cardioelectric monitor, is asked then being just able to solve this
Topic.In order to solve this problem, then requiring to check that the instrument of electrocardiogram should be sufficiently small, and electrode should lack as far as possible,
It is easy to operate using simple.
Band electrocardiogram function Intelligent bracelet product is numerous currently on the market, for example AMAZFIT meters of dynamic healthy bracelets, ori are special
Intelligent bracelet, dido smart motion bracelet, jsk Intelligent bracelet etc.；In fact such as with electrocardiogram function smartwatch class
Apple Watch Series4, Ba Dun N58 smartwatch, Fu member of Imperial Academy's smartwatch etc. are also Intelligent bracelet in fact, only not

Logical Intelligent bracelet and smartwatch are referred to as Intelligent bracelet.Electrocardiogram Intelligent bracelet the most commonly used is simulation both hands lead (I lead),
Meet the needs of user carries out quick ECG detecting, when needing ECG examination on the other hand with bracelet, in addition contacts hand on the other hand
The electrocardio contact of ring, forming circuit generate electrocardio pattern；Such electrocardio equipment can only monitor a lead, can detect less
The partially arrhythmia cordis of (10-12 kind).Since bracelet needs user's contact that can measure, only it is able to satisfy in short-term on user experience
The scene of measurement can not carry out long-time monitoring, and the monitoring of single lead in short-term is usually without too for medical angle
More clinical meanings, but if capturing electrocardiogram when arrhythmia episode still has certain clinical meaning.In conclusion
Electrocardiogram bracelet can only monitor a lead at present, be simply possible to use in part Monitoring on arrhythmia, can not the inspection of row multi-lead electrocardiogram
It looks into and cardioelectric monitor, therefore can not be in the popularization and use in clinical position.
In fact according to electronics test philosophy, say it is all bipolar lead in any cardiac diagnosis lead system nature.It will be bipolar
The two poles of the earth (anode and cathode) of lead, which are placed in any two points on human body surface, can record electrocardio wave waveform.Standard lead system
We are often described as unipolar chest lead to the Wilson chest leads system of system, in fact and bipolar lead, only left upper extremity,
Treat as cathode (namely so-called indifferent electrode or reference electrode) in the central station that right upper extremity, left lower extremity are connected into.
Although right upper extremity-chest bipolar lead (CR lead) electrocardiogram and standard ecg leads there is difference,
Multinomial research both at home and abroad confirms CR lead electrocardiogram in clinical success application.CR lead is once successfully applied to heart disease diagnosis
About 20 years, so correlative study is relatively more.Having many bipolar chest leads both at home and abroad at present, (including CR lead, CL lead, CF are led
Connection, main research is CR lead) and conventional chest leads comparative study.Research shows that CR lead has quite compared with CL, CF lead
More advantages, and CR lead and conventional precordial lead electrocardiogram are quite similar.De Gasperi, R. N, McCulloh are tentatively ground
Study carefully and shows only can sufficiently analyze cardiac potential using only the bipolar lead of 2 electrodes, the bipolar lead of the research
Including CR lead, abdomen-upper limb lead (research is 2 bipolar leads being connected respectively with right upper extremity, left upper extremity on navel)；
De Gasperi, R. N, Duncan, R. CLowery, M. H, Chakko, C. S, Sequeira, R. F. study table
Although bright CR lead and the low wave amplitude of standard lead P, Q, R, S and T have smaller difference, the two electrocardiographic diagnosis concordance rate is close
90%；D. HMeneses-Hoyos J, Gonzalez-Tamayo A's research shows that CR lead and standard chest lead comparison do not have
There is the difference of significant meaning, can be used for the clinical diagnosis to arrhythmia cordis, myocardial ischemia, myocardial infarction etc..CR lead is easy
It uses, and is only required to 2 leads, electrocardiogram bracelet can be redesigned, be set using bipolar lead electrocardiogram
Meter, meets self ECG examination, the hardware of cardioelectric monitor, software requirement, to reach row ECG examination whenever and wherever possible and oneself
The target of my cardioelectric monitor.
Summary of the invention

Well with effect.
The design of electrocardiogram bracelet lead includes: 1. right upper extremities-chest bipolar lead (CR lead), can simulate chest leads,
Its cathode is right upper extremity, and positive position is consistent with the V lead of Wilson lead system；2. I lead, cathode be right upper extremity (or
The lower section of clavicle outer 1/3 on the right side of person), anode is located at left upper extremity (or lower section of left collarbone outer 1/3)；3. II lead is born
Extremely just extremely (or left anterior axillary line is on rib lower edge and ilium for left lower extremity for right upper extremity (the perhaps lower section of right side clavicle outer 1/3)
Edge midpoint).Bipolar chest leads include CR lead, CL lead, CF lead, and Fontaine lead is also referred to as bipolar chest leads, also
Exercise testing also has exercise test also useful bipolar chest leads, easily causes name disorder；And this research not only includes upper right
Limb-chest bipolar lead (CR lead) further includes I lead, II lead, and it is right upper extremity that all leads, which are all made of cathode, so in order to
It is convenient intuitive, it renames as right hand lead (Right Hand Leads RH lead).Each lead is respectively designated as: RHC1
~RHC6, RH I, RH II, respectively correspond the V of standard lead1 ~V6,Ⅰ,Ⅱ.Unify RHC1 ~RHC6Equal chest leads are referred to as RHC
Lead is equal to pervious CR lead.RHC in fact1 ~RHC6It is exactly CR1 ~CR6Rename；RH I, RH II are respectively to mark
I lead, II lead of quasi- lead.
Conventional criteria lead electrocardiogram is derived by right hand lead: normal electrocardiogram lead even figure as shown in fig. 6, wherein R,
L, F respectively represents right upper extremity, left upper extremity, left lower extremity；Cathode is represented ,+represent anode；WCT is the central station Wilson；V generation
Table standard lead chest leads position, V1 ~ V6, take a point V to do and illustrate, wherein standard chest lead is indicated with Vn, the right hand by totally 6
Lead is indicated with RHCn.Potential is represented with E.I lead: electrocardiograph anode is connected in left upper extremity, and cathode is connected in right upper extremity.Therefore I=
EL-ER.II lead: electrocardiograph anode is connected in left lower extremity, and cathode is connected in right upper extremity.Therefore II=EF-ER.III lead: electrocardiogram
Machine anode is connected in left lower extremity, and cathode is connected in left upper extremity.Therefore III=EF-EL.According to above-mentioned 3 formula, III=EF- can be derived
EL=(EF-ER)-(EL-ER)=II-I.Similarly, III=RH of RH, II-RH I can be extrapolated.Central station (WCT) be R, L,
F connection central point, through mathematical computations EWCT=(EF+EL+ER)/3.VR=ER-EWCT=ER- (EF+EL+ER)/3=-
[(EF-ER)+(EL-ER)]/3=- (I+II)/3 VL=EL-EWCT=EL- (EF+EL+ER)/3=[(EL-
ER)-(EF-EL)]/3=(I-the III)/3=/ 3 VF=EF-EWCT=EF- (EF+ of [I-(II-I)]/3=(2 I-II)
EL+ER)/3=[(EF-EL)+(EF-ER)]/3=(III+II)/3=(II-I-II)/3=(2 II-I)/3 in order to
Improve unipolar extremity lead voltage, nineteen forty-two Glodberger modifies the centra electric terminals of Wilson, centra electric terminals with detect
That limbs is detached from, and obtained current potential is increased to half, calculation formula is as follows.AVR=ER- (EF+EL)/2=3/
=3/2VR=- (I+II)/2 2ER- (EF+EL+ER)/2=2/3 [ER- (EF+EL+ER)/3] similarly, aVL=3/
2VL=(2 I-II)/2=I -1/2 II；AVF=3/2VF==(2 II-I)/2=II -1/2 I.Lead Vn is that anode is connected in
Vn, cathode (no dry electrode) are connected in WCT.Therefore Vn=EVn-EWCT.Lead RHCn is that anode is connected in Vn, and cathode is connected in upper right
Limb.Therefore RHCn=EVn-ER.Thus it can be inferred that: Vn=EVn-EWCT=EVn- (EF+EL+ER)/3=EVn-ER+
[(EL-ER)+(EF-ER)]/3=RHCn- (I+II)/3.By above formula, this study demonstrates that relying solely on 2 electricity
The right hand lead electrocardiogram system of pole can be inferred that conventional criteria lead electrocardiogram by computer disposal after acquiring data.
I lead, II lead, III lead, aVR lead, aVL lead, aVF lead, each Vn lead of the chest leads difference of conventional criteria
With RH I, RH II, II-RH I of RH,-(I+RH II of RH)/2, I -1/2 RH II of RH, II -1/2 RH I of RH, RHCn- (
II)/3 I+RH of RH is substituted, to export standard ecg leads.Because right hand lead electrocardiogram newly puts forward, and
Most people also have little understanding to CR lead, so converting out standard ecg leads through computer is conducive to opening for clinical position
Exhibition, is also beneficial to analyze electrocardiogram.Pay attention to RH lead system RH I and RH II positioning and the difference of standard lead system, also
Electrocardiogram is not multi-lead synchronous acquisition, so heart rate difference is closed again after constantly first correcting when calculating later period synthesis electrocardiogram
At even if calibrated, itself is there may be deviation, but although bracelet acquisition electrocardiogram is not synchronized, but when because of interval
Between it is very short, heart rate variability is small, after correction its influence very little.
