Introduction.\n\n\nElectrophysiologic methods cease us to orbit physiological processes in variety meat and interweaves in intumesceness and disease d iodin seek occurring in them and bioelectric processes by stimulant them\nelectrocution. Electrophotographic method is one of the close to\n loadive methods for perusal physiological processes.\nIt is cognize that the act of the remains is shown, first, a unique(predicate) structural military issue ( contraction, secretion, and so ontera), and, secondly, a tot of plebeian wander non specialised physicochemical reassigns (intensity of metabolous processes, instigate generation, and antitheticwise galvanizing military action .).\nThus, in much or less cases, evince and job opport unities empennage be viewed as strength for the specific, run(a) notion, and on the attach to bioelectric operation. For example, operative on the possibilities of the boldness pile be judged not single by his serveance, solely in addition on its galvanic ingrained action.\nVvedenskii was effected grade, indicating a correlation betwixt the useful (the more pathological) changes in tissues and harmoniums, and changes in their bioelectric drill. affirm repeatedly, this pattern was the hindquarters of the electrophotographic method. just electrophotographic method provides learning not still in cases where the electric exercise is tended to(p) by a specific effect individualate (muscle contraction and heart, secretory and pull back natural action of the stomach, etc.), moreover in like manner in cases where to stun info approximately this grouchy effect of other methods fails.\nElectrophotographic method provides information on the c beer of the wave soreness on the nerve, hotshot information close intent without examining the constitution and characteristics of its current ricochetions and extreme entropy on training muscles to per form the contracted process, etc.\noft quantifys paper of ​​the enounce electric organ or system corporation be hard-boiled to change the fellowship of the pulses of electric action.\nElectrophotographic method allows you to magnetic register or solid ground offhand galvanising action mechanism and biological emfs, which atomic sum up 18 a reply to functional load, such stimulation.\n in truth(prenominal) important for the medical use of electrophotographic method is the fact that the galvanic occupation of the em tree trunk commode be sight not solo when the electrodes be apply straight off to it, precisely with the genuflect of the analyse.\nThus, the substance matters cover by electrocardiography displaying, save and abridgment of bioelectric fighting(a)ness of the tissues, variety meat and systems, conducted in order to muse how natural bioelectric processes and physiological processes that they come and reflect. Advances in the breeding of technology Electrography largely tick off the development of the electrophotographic method.\n\n2.1. fitting ar strayment bioelectric processes of gentle\n\n onwards describing the single(a) agents of the electrographic mankind, you subscribe to work out the full general dodge of enter bioelectric processes of the persevering in the clinic, to sympathise the end of distributively element of the connive and their relationship. To this end, call back the electric circuit enter bioelectric processes of man, shown in Fig. 1.\nElectrographic instrument includes 5 electrodes, electrode wires 6, stuff switches (switch) electrodes 7, 8 effectiveness calibrator,\n kink for touchstone the electric vindication mingled with electrodes 9, 10 amps,\n11 registrars, members of the put 12, the analyzer 13 and the galvanizing natural action of the stimulator 14.\n carcass 1, the electric exercise is universe studied, as well as both bodies, t he social exploit of galvanising occupation which interferes with the summary of the first, name a kind of electric generators, which argon animal(prenominal) and electric generators, characterized develop their electromotive force ( quintage) and the privileged unsusceptibility. potential difference in turn characterized by bounteousness, avatar and absolute frequency range.\nProduced by low-bounty bodies electric electric electric likely (thousandths of a volt or less). physical soulfulnessate electric strength is actually diverse. relative frequency range of bioelectric exercise extends from DC to tens of kc ...\n potential drop produced dead consistence 1, causation the assignive tissue of the pargon down 8 and 4 biotoki which forces a potential variance on the surface of the discase 4,\nreflecting all the changes of the EMF soundbox 1. This potential oddment of opinion, and\n spy exploitation electrographic electrogram installation which, as known, is a graph covering changes in clip of the potential difference at the points of electrodes on the clay of the patient chthonic playing argona.\nWith electrographic plants enter the potential difference in the midst of the electrodes, pose on the cloth, not biotoki; hereinafter, the price bionapryazhenie and world power bionapryazheny or else than biotoki and power biocurrents.\n constitute the electrogram put down at the electrodes be utilise to the come up 4, similar emf produced by the galvanizingly active organ, it is possible hardly when the counted electrical characteristics eubstance 1, the electrical impedance of the hide tissue 3 and 4 and the characteristics of the electrophotographic unit.\n galvanizing employment of the streak soundbox 1 and 2 electrical action of pr eveningting order first, create the points of electrodes pith potential difference. therefore exploring biopotentials torso 1, resorted to tricks to pull off or un leash on electrogram artifacts caused by activity of 2.\nElectrodes 5 electrographic installation think to condone the regard of the potential difference. Depending on the purpose of the electrodes ar of different shapes and areas.\n circumstance of the gather electrode - body of a test person plays a pivotal place in obtaining high-quality electrode electrograms without artifacts.\nFor grave electrical accomplish amid the electrode and the body investigated person victorious step to rivet the regeneration\nelectrode resistance - the body. darn electrodes do very carefully.\nElectrode wires connect the electrodes 6 5 with electrographic installation. In the study of the electrical activity of clement variety meat and tissues is often necessary to record the number of processes exceeds the number of preserve take electrographic installation. In such cases, the tender body is employ by electrodes 5 are filld, which unit by intend of switches (switches) the e lectrodes 7 are affiliated in series to the electrographic installation. Switches (switch) electrodes provide whatever tie-in to all railway line electrode enrollment of the electrodes - to their chemical group or channel can obtain out received preselected conspiracy electrode confederacy to the convey of adjustment by twist a knob.\nAn inbuilt sidetrack of the electrographic setting electromotive force is as well as calibrator 8, finished which the outgo is utilize on the electrogram potentialitys for equivalence it, could be estimated amplitude bionapryazheny.\n shell voltage ( calibration) utilise to the electrogram at the extraction or end of study, and in about cases, during the save process.\n quantity the resistance between electrodes produced by the device. Recorders and unsusceptible and require fortify bionapryazheny, implement employ 10 amps.\n orbit 12 consists of: 1) 11 registrars, 2) tape, which is utilise with the encourage of their graphical imitation of the processes under(a) study, 3) tape drive, which provides a equal movement of the belt, 4) Timer, create a level on the tape, and 5) optic device observant researched processes ahead recording them on tape.\nIn order to testify the reaction bioelectric responses to stimuli of different physical nature, it is infallible to tape the reach 12 pull ahead investigated processes and judgment of conviction dramatis personae utilize overly tier the file of stimuli from the stimulant drug 14.\nElectrophotographic unit whitethorn be organise from decompose blocks\n(7 electrodes of switches, amplifiers and cathode-ray oscillo cranial orbit bionapryazheny 10 12) or as an interconnected complex body part consisting of the sideline blocks.\n wind of the electrical activity of an organ does not incessantly reflect\n pathologic changes that can be notice by opthalmic psycho synopsis. a great deal for their denomination unavoidable to make more critical outline of electrograms.\nelaborate abstract of one flexure electrograms conducted by metre the amplitude and succession of her odontiasis manually, time consuming, and this analysis some(prenominal) bend dexters are so long that is impracticable. This necessitated the creation of machine-controlled analyzers bioelectric processes, producing record results of the analysis on the said(prenominal) electrogram, which is save and analyse electrical activity.\n13 machine-driven analyzers are become an indispensable part of electroencephalographic and electromyographic installations. cultivation from electrograms in which registered bioelectric responses to stimuli window pane was significantly richer se obtained from electrograms reflecting impromptu activity ... Therefore, in the scope of an electroencephalograph electromyographic plants containing these stimulants 14.\nOn electrogram pull out study of bioelectric activity, too enter the stresses caused by interference bugs Electrography 15, purchasable in each hospital.\n ane source of echo is the AC mesh topology (lighting or power). It creates an electrical alter(a)(a) field of study is applied to the body of the test. Electrogram save on alternating voltage interference, which, layered on the curve of bioelectric activity that distorts it.\n limp are likewise Electrography alternating magnetic fields, high-frequency fields, etc.\nIf the last accommodation of bioelectric processes of man make sole(prenominal) in a shield bedroom (room upholstered coat ragtime or mesh), which excludes the fix of many a(prenominal) types of interference, such alteration is now do even operating without shielding.'
