The medical community by the beginning of 21 centuries has determined quite a small place in clinical practice for computer’s (РС) analysis of the electrocardiograms (ECG), on the score of that such analysis yield in accuracy to the electrocardiologist assessment of arrhythmias diagnostics and can be useful only to the physician insufficiently knowing the diagnostics of ECG. The question whether the РС scan of ECG can be useful to the patient is not discussed at all. At the same time, from our point of view, in a century of telecommunications there was a background for wider use of РС ECG in preventive cardiology. It is a talk about the possibility which is provided by means of telecommunication for transporting ECG directly at the moment when, from the point of view of the user, it is important (feeling sick, cardialgia, arrhythmias etc.). This exact possibility has created the preconditions for registration and transfering the ECG in 12 leads to a server for further РС analysis and giving to the user a preliminary conclusion by the results of testing the rhythm (RA) and PQRST complex analysis. Such a preliminary conclusion of РС ECG with the classification of RA and PQRST complex, by "normal, deviation from normal and pathological" (a mode called "traffic lights") can be useful for self-rating a condition of a patient. Besides, an opportunity of access to a server for screening the ECG by the physician permits to reduce the probability of errors in РС analysis of ECG. We created the device called "Home-cardiometr", which is passing clinical tests now. It allows the user at any moment to register an ECG in 12 leads, and to transport a ECG with the help of Bluetooth of a mobile to a server for receiving preliminary РС ECG conclusion about the condition of RA and PQRST complex on the mobile phone screen in a mode of "traffic light". Such preliminary information allows the user to supervise his|her condition and in case of getting an alarm sign (pathology), to address it to the adviser-cardiologist, giving the access to the owner’s archive of an ECG of a server. First 150 ECG were sent by different consumers in such a way to a server. The preliminary РС ECG conclusion were received. The results had shown that during the РС analysing of the pathological electrocardiograms (with Q-myocardial infarction), there were not even one false negative РС ECG data. The screening of normal electrocardiograms in 20 % of cases has given false positive, overdiagnosis of РС ECG conclusions, which from our point of view is quite acceptable, due to the fact that false positive conclusions can be sifted by physicians. The further growth of the developed system will let the patient register an ECG singly, by himself in urgent cases, that can ease the diagnostic searching of coronary and arrhythmic events.
