[Arrhythmogenic dilated cardiomyopathy]

Abstract

Sustained or chronic tachyarrhythmia can produce reversible changes of atria or/and ventricles that induce systolic or/and diastolic disfunction, dilatation of heart chambers and progressive symptoms of heart failure. The changes regress after restoration of sinus rhythm. This is the clinical case, when at the beginning of the treatment, primary dilated cardiomyopathy is diagnosed to the patient having chronic atrial fibrillation and later after restoration of sinus rhythm and subsequent reduction of heart chambers as well as improvement of systolic function, past changes was assessed as reversible arrhythmogenic cardiomyopathy.
