[Electrocardiologic opportunities for the treatment of recurrent ventricular tachycardia on the example of a patient with arrhythmogenic right ventricular dysplasia].

Arrhythmogenic right ventricular dysplasia is a genetic disease, in which pathologic fibrofatty tissue occurs mainly in the right ventricle of the heart. Changes in heart muscle predispose to arrhythmias such as ventricular tachycardia or ventricular fibrillation, so these patients are candidates for implantation of implantable cardioverter-defibrillator. Furthermore, depending on the indication, RF-ablation is performed, which, due to changes in morphology of the heart muscle, are often difficult and of uncertain efficacy. In this paper we present a case of a patient with implanted cardioverter-defibrillator for primary prevention of sudden cardiac death. Initially, the patient experienced only complications related to the possession of the device, but due to the significant progression of the disease and symptoms, the device turned out to be necessary. In addition, the patient underwent complex electrophysiology procedures to control recurrent episodes of ventricular tachycardia. Treatment of cardiac arrhythmias in arrhythmogenic right ventricular dysplasia is problematic both because of the inability to predict the course of disease in asymptomatic patients, as well as due to the difficulty of carrying out effective ablation of arrhythmia foci in morphologically altered myocardium.
