Abstract
Abstract Introduction Purpose. To study the relationship between the indices of mechanical dispersion (MD) of the left ventricle and ventricular arrhythmias (VA) by classification Lown and Wolf in patients who have suffered a left ventricular myocardial infarction Methods The study included 80 patients with chronic CAD aged between 38 and 84 years. All patients underwent the following examinations: physical examination, general clinical and laboratory blood tests, 12-lead ECG, 24-hour holter monitoring; standart transthoracic echocardiography, assessment of left ventricular systolic function, speckle-tracking echocardiography with assessment of global longitudinal strain (GLS) and mechanical dispersion (MD) using the auto CMQ program on the Phillips Affinity 70 ultrasound machine. All patients divided into 5 groups: Group I - 22 patients without VA; Group II – 15 patients without ventricular arrhythmias. Conclusion The study shows that mechanical dispersion of the left ventricle is a marker of the risk of ventricular arrhythmias in patients who have suffered acute myocardial infarction of the left ventricle and the higher the gradation of arrhythmias, the longer the duration of MD
