METHOD OF PREDICTING AND STRATIFICATION OF DEGREE OF RISK OF DEVELOPING HEART VENTRICULAR ARRHYTHMIAS IN PATIENTS WITH ARTERIAL HYPERTENSION Russian patent published in 2012 - IPC A61B5/402 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used in cardiology. Registration of signal-averaged electrocardiography of high resolution is performed before and after physical exercise on the treadmill. Assessment of dynamics of changes of index of filtered complex QRS (Total QRS) duration is carried out. On the basis of the analysis of HR ECG data, before and after physical exercise, percent of increase of filtered complex QRS duration - Δ% TotalQRS is calculated by formula. If Δ% TotalQRS value is higher than 30% probability of arrhythmia development is estimated as high, if values are in the range from 20% to 29% including - as medium and if values are lower than 20% - as low.

EFFECT: method makes it possible to increase accuracy of arrhythmia prediction in patients with arterial hypertension due to taking into account dynamics of changes of electric inhomogeneity of myocardium under physical exercise.
