Changes in blood pressure during the day lead to the development of left ventricular (LV) remodeling, which includes the processes of hypertrophy and dilatation, changes in geometry and impaired contractility of the myocardium, which manifests itself in a violation of its diastolic function. Structural changes in the LV are accompanied by an overload of the left atrium (LA) and is a factor predisposing to the development of rhythm disturbances. Indices of EDV by 9%, LVM by 34% and LVMI by 71% were higher in the group of patients with hypertension and heart rhythm disturbances; LV ejection fraction was 9% lower in relation to patients with AH without cardiac rhythm disturbances.

Key words: left ventricular remodelling, left atrial remodelling, cardiac arrhythmias, arterial hypertension, left ventricular myocardial hypertrophy.
