[Effectiveness of 1 of the specialized devices for mass cardiological screening of the population]. / Ob éffektivnosti odnogo iz spetsializirovannykh ustroistv dlia massovogo kardiologicheskogo obsledovaniia naseleniia.

The efficacy of a specialized device for automatic ECG analysis was appraised on the grounds of examination of 1,499 healthy and sick persons. The method makes it possible to detect 74,2% of patients with diseases of the cardiovascular system. Patients with ischemic heart disease were detected with the greatest reliability (over 90%). A high reproduction of the results on homogeneous contingents of healthy and sick persons is shown, which is evidence that the use of specialized devices for automatic ECG analysis should be recommended for the cardiological screening of the population.

[Algorhythm for automatic analysis of electrocardiograms in a special apparatus]. / Algeritm dlia avtomaticheskogo analiza EKG v spetsializirovannom ustroistve

An algorhythm for an automatic analysis of the ECG by using a special device is proposed for the purpose of identifying patients suffering from diseases of the cardiovascular system. The algorhythm is based on the utilization of simple electrocardiographic indications measured with sufficient accuracy on a real time scale (PQ, QRS, T1 configuration, amplitude of the R, S, T waves). With the algorhythm analysis of the ECG taken in patients with primary rheumatic heart disease, complicated mitral lesion, hypertensive disease, myocardialinfarction the ECG changes helped identify 70 per cent of the patients. The algorhythm proved highly effective in recognizing patients with ischemic heart disease. A correlation between the stages of the affection and the frequency of detected pathological ECG was established. The results of automatic evaluation were contrasted against the data subsequent to an ECG analysis made by the physician, both of these being in good accord.
