Arrhythmogenic cardiomyopathy as a complication of tachysystolic atrial fibrillation

The article presents a clinical case of a diagnostically difficult disease – arrhythmogenic cardiomyopathy in a patient with paroxysmal atrial fibrillation. The complexity of this diagnosis is due to the fact that it can only be made retrospectively, when after successful rhythm control, including cardioversion or ablation, the systolic function of the left ventricle is restored and clinical symptoms disappear. The issues of the prevalence of the disease and its place in the modern classification of cardiomyopathies are considered. The features of structural, functional and hemodynamic changes in the heart are noted. Modern approaches to the diagnosis of the disease and the choice of an effective treatment strategy are discussed.
