PREDICTION METHOD OF HIGH-GRADE VENTRICULAR ARRHYTHMIA IN PATIENTS WITH CHRONIC HEART FAILURE AND PRESERVED LEFT VENTRICULAR EJECTION FRACTION

摘要

FIELD: medicine.;SUBSTANCE: invention relates to the field of medicine, namely to cardiology. Echocardiography is performed and the thickness of interventricular septum, the end-diastolic volume index and the degree of diastolic dysfunction of the left ventricle are determined. Prognosis of high-grade ventricular arrhythmia in this category of patients is carried out with the help of the developed formula using the above mentioned predictors. At the value of the prognostic coefficient ≥ 0.4, high-grade ventricular arrhythmia in this category of patients is predicted.;EFFECT: method allows with high accuracy predict high-grade ventricular arrhythmia in patients with chronic heart failure and preserved left ventricular ejection fraction.;1 cl, 3 dwg, 2 tbl, 2 ex
