Abstract:
The article is devoted to the definition of cardiac arrhythmias and the establishment of the
relationship of the identified arrhythmias with changes in the geometric model of the heart in
patients with arterial hypertension (AH).
Material and methods of research. The study included 75 patients with AH. All the
examined patients underwent daily ECG monitoring. The structural and functional parameters of
LV were evaluated using echocardiography (EchoCG). As a result of the conducted studies,
changes in the geometric model of the heart were revealed in the overwhelming number of
examined patients with hypertension. However, there were certain features of heart remodeling
(HR) in each group of patients. Patients with concentric hypertrophy (CH) of LV dominated - 25
patients (33.3%). Eccentric hypertrophy (EH) of LV was detected in 20 patients (20%),
concentric remodeling (CR) of LV-in 14 patients (18.7%). Normal heart geometry was observed
in 21 patients (28%). The analysis of daily ECG monitoring revealed the following types of
arrhythmias: supraventricular extraа systole (SVE)-35%, ventricular extra systole (VE)-13%,
SVE=VE-45%, without rhythm disturbances-7%. When studying the heart rate variability
indicators depending on the types of left ventricular remodeling, the heart rate variability
indicators are the lowest in the group of patients with concentric hypertrophy and the proportion
of very low frequency waves (VLF) was the highest
