Description
Technical field
The present invention relates to cardioelectric monitor technical field, lead dynamic electrocardiogram particularly to a kind of based on wilson's lead2s 18
Figure analysis method and system.
Background technology
Heart is a three-dimensional organ, and the every electrocardial vector that produces in a flash in ignition process has certain space bit
Put, i.e. have the spatial relation of top to bottom, left and right, front and rear to reflect the vector of this solid, referred to as space vector.Due to electrocardial vector energy
Showing cardiac electrical phase relation, thus it is not enough to compensate for some on electrocardiographic diagnosis, electrocardiogram and vectorcardiogram are all bodies
Table gathers the main low-frequency component in ecg information, has the theoretical basis that it is common, and system of simply leading is different with expression way
?.
In current clinical routine electrocardiogram quasi-instrument used in everyday, usually the 3-12 synchronized sampling that leads shows.This
Very important effect is played in the use of a little instruments of diagnosis and treatment to(for) cardiovascular diseases clinically.But at common cardiac
Disease, especially in myocardial ischemia disease, disease incidence position is often not only limited to conventional 12 and leads, such as the common acute heart
Flesh infarction, if betiding left ventricle antetheca, relying primarily on and observing the ST-T change that front V3, V4, V5 lead；If betiding a left side
Ventricle lower wall, then need to observe limb lead II, III, the ST-T situation led of avF.Tradition 12 leads dynamic ECG system owing to leading
The restriction of connection still can not the most objectively be observed and judge the positive rear wall in left room and RV myocardium ischemia and the ECG change of damage.
Patent (application number: 201110006863.6；Title: a kind of synchronism output electrocardiogram and vectorcardiogram of realizing
Method) propose the 12 of a kind of Wilson of employing central electric terminal and lead electrode is obtained the signal of telecommunication input of human body, use anti-throwing
Shadow calculating formula can by electrocardiogram back projection measured directly obtain synchronization vectorcardiogram, it is achieved that electrocardiogram and
The electrocardiogram output scheme of the synchronism output of vectorcardiogram, but the program is still and can only realize 12 and lead synchronized sampling, nothing
Method realizes 18 synchronizations led and uses, thus can not judge the positive rear wall in left room of patient and RV myocardium ischemia and damage by complete observation
The ECG change of wound, is delayed the state of an illness of patient.
In existing Electrocardiography, lead cannot realize for special case routine 12, need to add multiple leading again,
Such as 18 lead could realize detecting completely, and this mode efficiency is low, degree of accuracy is the highest, and equipment is complicated, brings not to patient
Just.
If patient suffers from acute right ventricles and left ventricle positive rear wall myocardial ischemia disease, often lead 12 clinically
On the basis of add again and be V3R, V4R, V5R tri-and lead.When left ventricle positive rear wall myocardial ischemia disease, often lead 12 clinically
Add again on the basis of connection and be V7, V8, V9 tri-and lead.Common practices of the prior art is: finish conventional 12 lead after, then will
6, front electrode extend the most to the left and right add be V3R, V4R, V5R and V7, V8, V9 lead.This mode not only wastes time and energy, also
Lead with above-mentioned 12 and cannot synchronize same source sampling Synchronization Analysis.

The planar rings that projection is formed, referred to as plane of structure Heart vector ring.Parallel rays is radiated at ring body from Right vertical, its left surface
The planar rings that projection is formed, referred to as right flank Heart vector ring.This is the first time projection of space Heart vector ring.Clinically, use
Vectorcardiogram represents.By the every bit reprojection successively of above-mentioned face amount vectorcardiographic loop on each limb lead axle, recordable
Go out the electrocardiogram of each limb lead；The projection on each chest lead axle of the plane of structure Heart vector ring, can trace out each precordial lead electrocardiogram.
This is the second time projection of Heart vector ring.Must project successively according to the sequencing that Heart vector environment-development is raw during projection；By the heart to
Tangent line the most at a right angle with each axis of leads is made at the edge of amount ring；The positive side being projected in axis of leads obtains ripple upwards, is projected in and leads
The minus side of axle obtains ripple downwards.
Specifically, according to X, the Y obtained and the data of Z axis, plane is formed with face amount, plane of structure, side projection index variation
Electrocardial vector, wherein, the projection on I, II, III, X, Y and Z axis of the plane vectorcardiographic loop of face amount corresponds to the limb of measured
Body lead electrocardiogram.
The projection on limb axis of leads of the face amount Heart vector ring:
(1) I leads, and P ring projects to the positive side of I axis of leads, therefore the I upper P ripple that leads is forward wave.The start-up portion of qrs loop
Projecting to the minus side of I axis of leads, electrocardiogram shows as q ripple, qrs loop maximum vector projects to the positive side of I axis of leads, electrocardiogram
On show as R ripple, so I upper QRS groupuscule of leading is qR type.T ring projects to the positive side of I axis of leads, and electrocardiogram recorded one
Individual T ripple upwards.
(2) aVR leads P ring and T ring is all projected in the minus side of aVR axis of leads, and therefore P ripple and T ripple are the most downward.Qrs loop rises
The maximum vector begun projects to the minus side of aVR axis of leads, obtains Q ripple downwards；Rear sub-fraction vector projection is at this axis of leads
Positive side, obtains r ripple upwards；Therefore, the QRS complex that aVR leads is Qr type.
The projection on I, II, III, X, Y and Z axis of the plane vectorcardiographic loop of plane of structure corresponds to the chest lead heart of measured
Electrograph, Fig. 6 is the schematic diagram of the plane of structure plane vectorcardiographic loop according to the embodiment of the present invention.
The forward part of P ring is projected in the positive side of V1 axis of leads, and rear section is projected in minus side, therefore the P ripple that V1 leads is in the most just
Rear negative bimodal P wave.The forward part of qrs loop is projected in the positive side of V1 axis of leads, forms r ripple, and major part is projected in minus side, shape
Becoming S ripple, therefore the V1 QRS complex that leads is rS type.T hoop amount is projected in the positive side of V1 axis of leads, therefore V1 leads in T wave direction.
The projection on I, II, III, X, Y and Z axis of the plane vectorcardiographic loop of side corresponds to the Ventricular of measured
Lead electrocardiogram.
The present invention forms plane vector figure with face amount, plane of structure, side projection index variation, is projected out N number of leading at 0-360 degree
Shaft coupling compensate for the angle blind area of the sidewall in Electrocardiography and rear wall.
Being Heart vector reprojection theory according to electrocardiogram formation basic theory, routine electrocardiogram is face amount, plane of structure Heart vector ring
Projection on leading conventional 12, and the permutation and combination face amount that X, Y, Z axis is different (X+Y axle), plane of structure (X+Z axle) and right flank (Y
+ Z axis), three-dimensional Heart vector ring projects on these three and forms vectorcardiogram.
Thus triadic relation is close, conventional leads standard I lead aVF lead and V1 or V2 lead respectively with X, Y, Z axis phase
When.X and Y-axis orthogonal ECG can reflect that face amount Heart vector ring changes, X and Z axis orthogonal ECG can reflect the plane of structure heart to
Amount ring changes, Y and Z orthogonal ECG can reflect that right flank Heart vector ring changes.
In other words, about vectorcardiogram, up and down, the change of front and back current potential, the numerical value in three faces and vectorcardiogram with
The numerical value of orthogonal ECG should be on all four.The size of face amount and transverse plane QRS loop vector to the left, should be with the R ripple size of X-axis
Consistent, the size of face amount and right flank qrs loop vector downwards, should be consistent with the R ripple size of Y-axis, plane of structure and right flank QRS
