At the top of each display angle take the center of the screen indicator. About the functional state of the organism represented by the figure on the screen of the indicator. The method allows to obtain a visual representation of the condition of the examinee. 3 Il. The proposal relates to the field of clinical medicine "diagnostic testing" and can be used in everyday medical practice, and for individual use for preventive examinations.Currently, it is well known that the functional state of the organism can be determined according cardiology studies, such as the rhythmogram, representing a temporal sequence, elements to the adjacent R teeth of each cardiac cycle, called R-R intervals. (See, for example, P. M. Baevsky "Automatic analysis of heart rate as a method of assessing the state of the organism under different influences. In the book "Theory and practice of automation electrocardiographic research, Pushchino, 1976, S. 129-130, P. M. Baevsky To the problem of predicting the state of the person in conditions of space flight "Physiological journal of the USSR, 1972, 6, S. 20-28, M. Kazakov, M. Brazhnikov I. R-R "Intervalografia research students, trainees work with a personal computer", human Physiology, 1991, T. 17, 5, S. 151, and others ).There are many methods and devices allowing to determine the functional state of the organism as a whole and its individual systems and organs: cardiovascular system, respiratory organs, etc., (see, for example, certificates of authorship and patents: Russian Federation 2020864, IPC: 61 5/02, 2036605, IPC: 61 5/0205, 1258374, IPC: 61 5/04, 1258384, IPC: 61 10/10, USA 4583553, IPC: 61 5/04 (NCI: 128-704), 5348020, IPC: And 61 IN 5/04 (NCI: 128-696), 5343869, IPC: 61 5/04 (NCI: 128-700), 5357969, IPC: 61 5/04 (NCI: 128-696), 5355889, IPC: 61 5/0205 (NCI: 128-671), 5339822, IPC: 61 5/04 (NCI: 128-700); Germany 4238641, IPC: 61 5/0295; France 2701380, IPC: 61 5/04; Japan 5-46216, IPC: 61 5/11, 5/05, 5-45257, IPC: a 61 B 5/0452; PCT 94/240929, IPC: 61 5/00, 5/0444 the isolation sinus of the heart healthy and the sick." In the book "Analysis of cardiac rhythm" edited by Zemaityte D., Telcyta L., Vilnius: Mokslas, 1982, S. 24, and others).Most of the known methods and devices are used as source data indicators electrocardiogram (ECG), such as a sequence of R-R intervals, heart rate, etc., the decision about the functional state of the organism on the processing results, which are in the form of histograms, spectrograms, etc. displayed on the screens of electronic indicators in digital or analog form, on paper strips of different recorders, etc.Despite the sufficient accuracy of the final solution, the disadvantages of the known method of processing and displaying cardiac information should include the lack of visibility of the displayed information, which entails the possibility of serious errors in the estimation of the functional state of the organism, especially in the case of individual use, when the monitor display screen is the operator, not having sufficient experience and knowledge. The only exception is the display of information in the form of a histogram distribution of the values of R-R intervals, for deciding Pharmacia only about the likelihood of a particular value of R-R intervals.The closest in technical essence is a method of processing and displaying cardiac information, known from an article by Zemaityte D. I. "Autonomic regulation of heart rate in healthy volunteers and patients" (see the book "Analysis of cardiac rhythm. Edited by Zemaityte D., Telksnys HP - Vilnius: Mokslas, 1982, S. 28-31).The known method is that the subject is removed electrocardiogram (ECG) to measure the intervals between R teeth adjacent cardiocycle, and they build ramagrama (WG).The last or set some of its parameters display on the screen of the indicator (see the above article, S. 28, Fig.4). In addition, a spectral analysis of the ECG, the results of which are displayed on the screen.Thus, for a decision to the operator show respectively the WG, and the histogram of the values of R-R intervals, spectrogram, etc.,The disadvantage of this method is the abundance of information, which receives the operator, thereby increasing the time a decision, because before you make a decision about the functional state of the organism of the subject the operator to see and estimate separately each of the species presented info is inogo state, and only then take a decision.The main task, which is aimed invention is to provide definitions of the desired option displayed on the screen of the indicator allows you to take a reliable decision about the functional state of the body examined by a single monitoring screen.To solve this problem, a method for processing and displaying cardiac information, in which, as in the prototype, with the subject remove the electrocardiogram, which build ramagrama and determine the sequence of respiratory waves.Unlike the prototype, the proposed method the ascending and descending branches in each respiratory wave approximated by straight lines connecting the maximum value of R-R intervals in this respiratory wave with left and right minimum values, measure the angles of the ascending and descending respiratory waves, transpondeur the magnitude of the angles in the desired sector, and displays a set of angles on the screen of the indicator, taking over the top of each display angle of the center of the screen of the indicator and educated on the screen of the indicator image decide functionvariable is that is, by determining the angles of the ascending and descending branches of each respiratory waves, the view angles on the screen of the indicator and the adoption of the decision on the image on the screen of the indicator, the opportunity to take a reliable decision about the functional state of the body examined by a single observation on the screen.In Fig. 1 and 2 show diagrams explaining the essence of the proposed method, Fig.3 - species screen indicator for the case of normal functioning of body condition and operation condition of the body, with pathological deviations.The claimed method consists in the following.With the patient ECG is performed, which determines the sequence of R-R intervals. This sequence build the WG, and it found a DV sequence, the parameters (duration, number of R-R intervals, forming DV, etc.) characterize the functional state of the organism (see, for example, Zemaityte D. I. "Autonomic regulation of the sinus of the heart healthy and the sick." In the article "heart rate Analysis" edited by Zemaityte D., Telcyta L. , Vilnius: Mokslas, 1982, S. 22; M. Kazakov, M. Brazhnikov I. "R-R intervalografia investigated the Yu LW is defined as the number of R-R intervals between two adjacent minimum values of R-R intervals, both the minimum value, as the right of the inflection point of the active ingredient, and to her left, another LW.After the WG determine the sequence of the active ingredient, the branches of each DV approximate straight lines: the ascending line connecting the maximum value of R-R intervals with a minimum value of lying to the left of the inflection point, and a downward - line that connects the maximum value of R-R interval with its minimum value, which lies to the right of the inflection point of the active ingredient. Approximatives the ascending and descending branches of each DV direct, determine the angles between approximarely direct and the x-axis (Fig.1). Then display the set of angles on the screen of the indicator.The corners of the display as follows. At the top of all angles take the center of the screen of the indicator, and the zero line (one side of the displayed angles) take half of one of the lines dividing the screen into four parts, one positioned horizontally, the other vertically. The second side of the building at the required angle to the zero line, putting the desired angle counterclockwise (Fig.2).Since the angle of inclination of any branch of all DV is always less than the 90oto use the entire surface of the screen and more napadenie (Fig.2), values which, depending on the display conditions are chosen equal to two or four: two for the case of split screen angles of inclination of the descending and ascending branches, i.e. the case when the angles of inclination of the ascending branches DV displayed on one half of the screen of the indicator, and the angles of inclination of the descending branches to the other four for the combined display of the angle of the ascending and descending branches of the active ingredient, i.e., for the case shown in Fig.2.As shown by the results of research conducted by the authors, practically healthy people, i.e. the people, the functional state which can be considered normal, the value of the tilt angles of the active ingredient varies from values close to zero to values ( taking into account the coefficient of transposition), close to 360o). On the contrary, people in the body which are serious pathological deviations, the value of the angles of the branches DV (also taking into account the coefficient of transposition) are concentrated in the sector 270o-360o.The above is illustrated in Fig.3A, which shows the display screen with the indicated angles of the branches of the active ingredient during handling and displaying cardiac information in soulbody ECG practically healthy person (patient D). As shown in Fig.3A, the angle of inclination of the branches of the active ingredient in this case is more or less distributed over the entire surface of the screen, which characterizes a good functional state of the organism. In Fig. 3B presents a view of a display screen displaying the results of processing the ECG suffering from cancer (patient). As can be seen in Fig. 3B, the angle of inclination of the branches DV concentrated in sector 270o-360othat proves unsatisfactory condition of the body of the subject.Thus, as follows from the description of the proposed method, it provides a simple and reliable determination of the functional state of the organism. The proposed method requires minimal operator training, on the kind of the screen indicator decision-makers about the functional state of the organism, which is especially important when an individual method.The proposed method can be easily implemented using the device on the basis of the elements of the micro-circuitry, well known and widely used in modern electronic devices.

SUBSTANCE: the present innovation deals with measuring parameters of electrocardiosignal (ECS) ST-segment and their analysis to detect deviations against the norm. At every step of quantization one should form the readings of first-order differences and modules of first-order differences. One should memorize N of readings for the modules of first-order differences coming after ECS readings that correspond to the onset of cardiocycle. Then it is necessary to sum up memorized values of modules and at every step of quantization one should compare the obtained current sum value with previous one. It is necessary to memorize the greater of them and according to maximal value one should form threshold level to compare current value of modules sum. Time moments when sum value is at first greater and then lower against threshold level one should consider to be, correspondingly the onset and the end of ST-segment. Time segment between the onset and the end of ST-segment should be considered as duration of ECS ST-signal. Device to isolate ECS ST-signal on-line contains a block for forming ECS, a block for primary ECS processing, a quantization block, a block for isolating the point of cardiocycle onset and measurement of its duration, a block to form first-order differences, a block to form modules of first-order differences, a block to memorize readings for the modules of first-order differences, a block to detect the number of summarized readings for the modules of first-order differences, a summarizing block, a block to form a threshold level, a block for comparison and a key device. The innovation enables to isolate ST-segment more reliably for wider class of electrocardiograms at different modifications of QRS-complex form.
