DIAGNOSIS OF HEART RHYTHM DISORDERS AT EARLY STAGES OF LEFT VENTRICULAR REMODELING
Abstract
Objective: to study the features of cardiac arrhythmias during stanning of the left atrium at the early stages of left ventricular remodeling in patients with essential hypertension. Materials and methods: On the basis of the regional cardiological dispensary, a retrospective study of 73 outpatient records of patients with essential hypertension and rhythm disturbances at the age of 30 to 56 years was carried out. The observation period was 6 months. To assess the geometric model of the LV, we used the classification (normal LV geometry, concentric left ventricular remodeling - ECD, concentric LV hypertrophy - eccentric LV hypertrophy).
Results and Discussions: Patients were divided into 2 groups: 1- group of patients with essential hypertension without heart rhythm disturbances. 2- group of patients with essential hypertension and heart rhythm disturbances. In patients with hypertension without heart rhythm disturbances were found in the largest number of patients with concentric myocardial remodeling. Persons with concentric LV hypertrophy dominated in the group of patients with essential hypertension and cardiac arrhythmias. Heart damage in hypertensive disease is manifested not only by morphofunctional remodeling of the left ventricle, but also by changes in the electrophysiological properties of left atrial cardiomyocytes. The defining condition for the occurrence of cardiac arrhythmias is the presence of a structural heart disease - stanning of the left atrium.
