Description

Multifunctional automatic diagnosis and treatment instrument for complex electrocardio-activity

The present invention is the heart disease diagnosis and the therapeutic equipments in a kind of modern times.

Electrocardio-activity Clinics and Practices instrument is the treating heart disease imperative equipment.Since the mankind had invented electrocardiogram and vectorcardiogram, various electrocardiographs and ecg vector diagram were existing multiple.In " the practical electrocardiography " that the Shandong medical college is write, " electrocardial vector graphics ", the U.S. T.C.CHOU that Lin Shaofang etc. write shows in " CLINICAL VECTORCARDIO GRAPHY " Chinese and foreign documents such as (clinical electrocardial vector graphics) all full and accurate argumentation.As the standard cardioelectric figure instrument of energy measurement conventional leads, ecg vector diagram etc.These instruments can be finished 12 lead electrocardiogram, the drafting of the vectorcardiogram of single cardiac cycle.But mostly these instruments are single and detect, or limited comprehensive detection, thereby limitation is bigger, can not reflect the cardiac electrical activity situation all sidedly, can not catch the significant special electrocardiosignal of analysis simultaneously in many-sided ground again; Secondly present vectorcardiogram can only reflect single cardiac cycle, powerless to arrhythmia, the accurate location of ventricular premature contraction etc., manufacturing of the vectorcardiogram of particularly commonly using is very complicated, will by a series ofly take pictures, wash, process such as printing, cycle is long, operating process is loaded down with trivial details, brings difficulty to clinical practice; Since nearly ten years, though intracardiac/the adventitia mapping, His bundle electrogram and cardiac stimulation art etc. have one's own knack to diagnose arrhythmia etc., the diagnosis height, but belong to the inspection of wound property is arranged, the diverse location that needs to perform the operation and open the thoracic cavity or electrode catheter is inserted into the heart the inside along patient's artery and vein blood vessel, so that poor repeatability, dangerous big, technical conditions require is high, expense is expensive, also may not once can be successful, by patient is difficult to acceptance; And existing various detecting instruments all are limited to detection and do not have the function of treatment simultaneously.

The objective of the invention is to solve the deficiency of above-mentioned instrument, provide synchronous continuous integrated electrocardio-activity figure, observe electrocardio-activity at many levels, with multi-angle from time domain, spatial domain etc., carry out analytical judgment with computer, make a comprehensive detection cardiac electrical activity and have the instrument of treatment function concurrently, thereby reach accurate diagnosis, noninvasive test, the purpose of treatment in good time.

The objective of the invention is to realize with following scheme: leading existing 12 increases by 4 16 lead systems that line is formed 16 lines that lead that lead on the basis of system, synchronously gets 12 lead electrocardiogram (ECG) signals and orthogonal vectorcardiogram X, Y, Z lead signals from human body surface; Adopt the soft switch of micro-processor controlled electronic simulation, the signal that 16 lead systems are obtained extracts electrocardiogram, three groups of different signals of vectorcardiogram and complex electrocardio-activity figure on demand respectively; Adopt advanced micro-computer technology that each lead signals is carried out the A/D conversion, then, by microcomputer it is sampled, deposit the signal of adopting in internal memory, by a series of algorithm process and D/A conversion, draw successive electrocardiogram, orthogonal electrocardiogram, vectorcardiogram, time vectorcardiogram and ladder diagram synchronously again with drawing apparatus; Adopt micro-processor controlled cardiac stimulation signal output stage, S is provided ₁S ₂S ₃S ₄Four road stimulus signals are with the relevant heart disease of diagnosis and treatment.

The present invention can trace routine electrocardiogram, vectorcardiogram, orthogonal electrocardiogram, time arrow electrocardiogram, continuous EGC vector figure, esophageal pulsation modulation electrocardiogram, graph of heart (as atrium electrograph, His bundle electrogram, electroventriculogram, coronary sinus vein figure) synchronously and be used for the ladder diagram of arrhythmia analysis.Also can provide above-mentioned various figure on demand separately,, judge ARR mechanism, and can treat diseases such as supraventricular tachycardia to be used for different cardiopathic diagnosis.Now, under the noninvasive testing situation, can make space orientation to arrhythmia, as invisible premature ventricular beat, room/premature ventricular beat through the various cardiacs' of 100 Yus example clinical verification; The space orientation of ectopic excitement point is accurate, simple and clear than electrocardiogram, especially to multi-source, multiple premature beat level diagnosis be routine electrocardiogram can't be obtained.More in the past single diagnosis is simple and clear more, accurately in Differential Diagnosis, as the discriminating of indoor diversity conduction, a left side/right bundle branch block and premature beat, supraventricular and ventricular tachycardia and intermittent complete left bundle branch block and ILBBB etc.Judge that arrhythmia all has bigger breakthrough in ventricle level, junctional area level or atrium level.

The present invention will be further described below with reference to accompanying drawing:

Fig. 1 is the multifunctional automatic diagnosis and treatment instrument for complex electrocardio-activity system block diagram.

As shown in Figure 1, the present invention is in order to take out needed signal from human body surface, designed a kind of lead system [1] that 16 lines that lead are arranged, get 16 road signals from human body, this 16 road signal isolation level [2] by separately respectively arrives resistance and leads and select network [3], signal leads by resistance and selects exportable conventional leads electrocardiosignal and the orthogonal electrocardial vector signal of containing in network [3] back, these signals are sent to the soft switch of electronic simulation [4], according to clinical needs, the operator is by the signal of keyboard input regulation, by microcomputer [11] gauge tap [4], variously lead or lead composite signal to select, can select 12 road signals synchronously at most, these signals are sent to preamplifier [5] separately simultaneously, and preamplifier [5] is selected typical three amplifier differential amplifiers for use, is to have high input impedance, high-gain, the low-frequency amplifier of high cmrr, it is with the distortionless volt level that is amplified to of the signal of the microvolt level of body surface, so that with post processing.Signal after preposition amplification is sent to wave filter [6], and wave filter [6] is made up of low pass filter and 50HZ wave trap, in order to filter high-frequency noise and 50HZ noise.Filtered signal is again by one-level gain-adjusted level [7], to satisfy different needs, then, signal is sent to photoelectricity isolation level [8], adds photoelectricity isolation level [8], and the ground of prestage and the ground of microcomputer are kept apart, thereby reduced earth-return, reduced interference noise widely,, guaranteed the safety of tested human body simultaneously also with prestage and isolated from power.Signal passes to by the photoelectricity isolation level and reaches sampling holder [9], and analog digital conversion (A/D) device [10] takes turns to carry out the A/D conversion to each road signal of sampling holder [9] output, sends into microcomputer [11] internal memory then.Can handle the data of internal memory by microcomputer [11] as required afterwards, arrive drawing apparatus [13] by digital-to-analogue conversion (D/A) device [12] at last, depict needed various electrocardio-activity figure.In addition, according to the needs of treatment, the different control signal of may command microcomputer [11] output arrives stimulus signal output stage [14], so produce four stimulus signal S that output is different ₁S ₂S ₃S ₄, so that clinical diagnosis and treatment.
