[Algorhythm for automatic analysis of electrocardiograms in a special apparatus]

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.
