Description
Technical field
This utility model relates to a kind of Array ECG Signals processing system, especially relates to a kind ofly based on Array ECG Signals, realizing the space vector figure of heart and the system equipment of space kinetocardiogram under the support of human body holographic theory
Background technology
To learn according to heart solution born of the same parents and the periodic depolarization of resting potential of heart electronics myocardial cell, process of repolarization are the basic activities of generation electrocardiosignal
Myocardial cell is functionally mainly divided into self-regulating functions cell, contractile function cell.Self-regulating functions cell completes depolarization, process of repolarization automatically by some cycles, produces electrostimulation.Contractile function cell receives excitement, triggers depolarization, multipole, and sarcostyle is shunk.Self-regulating functions cell concentrates on sinuatrial node, so the initial electrostimulation of one-period originates from atrium.
The depolarization of a cell and process of repolarization are very fast, between 0.1-1 millisecond, are in waiting state afterwards, it again depolarization need conduction come excitement stimulate.Only have the autorhythmic cell of atrium sinuatrial node after a cardiac cycle finishes, automatic excited, the depolarization again of meeting, and pass under excitement.
Any cell has excitatory transmission function, but Xinier reservoir (i.e. atrioventricular bundle, is connected with atrioventricular node) left and right chamber bundle branch (primarily of Purkinje cell composition) conduction velocity is fast, conduction velocity be atrium, 3 times-5 times of locular wall.Left and right Xinier reservoir props up and is distributed in left and right ventricles spaced walls.So it is interventricular septum that the excitement of ventricle first betides.This structure causes sequences of ventricular depolarization process of excitation more complicated, makes each part of ventricle not start depolarization in the same time.
Crackled with excitement is depolarization, the multipole activity of phalangeal cell.Comprehensive electric power is produced, to the space radiation signal of telecommunication at the electrical activity of the cell excitement excitement of specifying the moment all possible.Signal of telecommunication radiation is moment.But the conduction of excitement is not signal of telecommunication radiation, the transmission but the crackled with excitement orientation between cell is shaken hands, so the conduction of excitement is not instantaneous, needs the time.Excited conduction makes each position crackled with excitement in an orderly manner of heart, and excited conduction is the conduction of electrical activity.
Electrical activity also causes myocardium convergent-divergent except radiation signal.It is the sarcostyle be made up of multiple protein silk around myocardial cell.The depolarization of cell, multipole activity (electrical activity) are to while the space radiation signal of telecommunication, cause sarolemma potential change, make calcium ion according to diffusion to sarcoplasm, be combined with actin filament, the enzyme decomposition triggering crin in sarcoplasm releases energy, make Filament slippage cause muscle segment to shorten, cardiac muscle fiber is shunk.When multipole, protease impels the calcium ion in sarcoplasm to be put away by sarcoplasmic reticulum, muscle fiber diastole.
The combined process of a cell mass forms its flesh block and shrinks, the contraction in atrium from upper right lower left peristaltic contraction, by blood expression to ventricle.Atrial cells completes depolarization completely, and atrium terminates to shrink.Excitatory transmission conducts to atrioventricular node and then by Xinier reservoir to ventricle, causes the contraction of ventricular muscles.Distribution left and right, interventricular septum both sides bundle branch, the same with Xinier reservoir is conduction fast, 0.5-5 rice per second.And locular wall cell conducts at a slow speed, 0.1 meter per second.So ventricle process is interventricular septum first depolarization, contraction, be then that locular wall inner membrance is to adventitia.This nonsynchronous contraction ensures that myocardial blood can flow out from the popliteal artery entrapment of ventricle smoothly, completely.
Find out from the mechanism of myocardial contraction, contraction dynamics and signal intensity are without direct relation.But be the synthesis of the depolarization of more cell at peak value place, also mean more cellulous contraction movement, the contraction intensity that the moment at signal peak place is corresponding is relatively larger.
For penetrating blood to tremulous pulse, the contraction dynamics of ventricle must be large.Ventricle folds in a garment is covered with Purkinje fiber.Purkinje cell except excitatory transmission soon except, its action potential rate of change is up to 1000V/S.Therefore, the depolarization multipole cycle is 100 Microsecond grades, and its muscle fibers contract time is also extremely short, and its contraction dynamics is naturally powerful.The rate of change of 1000V/S causes superradiance, so the QRS wave group amplitude of the comprehensive process of depolarization of reflection ventricle is also large, is the several times of P ripple.So although the dynamics of contraction and signal intensity are without direct relation, there is proportionate relationship in signal intensity and contraction dynamics indirectly.
So electrocardiosignal is the comprehensive electrodynamic embodiment of cardiac myocytes, and electrocardiosignal reflects cardiac function and physiological activity.
But, obtained electrocardiosignal from 1900 first and establish basic electrocardiogram, existing over one hundred year history so far.For over 100 years more than a hundred years, according to electrocardiosignal theoretical invention, create various non-invasive electrocardiogram equipment equipment.But these equipment are also just confined to the level of electrocardiosignal monitor level to the application of electrocardiosignal.These common electrocardiogram equipment equipment are under the electrocardiosignal measurement environment of two dimension at present, use single point signals to form one dimension EGC pattern and describe cardiomotility.The figure of single-point electrocardiosignal can not clearly state the functional activity of heart.So current electrocardiograph majority uses the figure of 6-12 electrocardiosignal to form electrocardiogram.In fact, even if 12 electrocardiogram equipments that lead can not describe the functional status of heart exactly.If increase more signal to build electrocardiogram, the difficulty of artificial interpretation can be caused.So, existing non-invasive electrocardio equipment to the understanding of the information that electrocardiosignal is carried and and use be incomplete, incomplete.This also causes these equipment at present can only play general reference role, plays the supervisory function bit of heart basic function.
So, need deeply to excavate heart physiological and pathological information that electrocardiosignal carries, from new visual angle, set up new electrocardiosignal application model, make non-invasive Electrocardiograph equipment can describe the functional status of heart more exactly, become one of relied on equipment of Diagnosing Cardiac function.
This utility model is for solving the problem and proposing.
