[Ventricular tachycardia in patients with arrhythmogenic right ventricular dysplasia. Electrophysiologic characteristics and testing of the effectiveness of anti-arrhythmia therapy].
The authors present a clinical and electrophysiological characteristic in two cases of symptomatic sustained ventricular tachycardia (VT) with a QRS morphology of left bundle branch block, refractory to common antiarrhythmic treatment. It was confirmed that the mechanism of this arrhythmia associated with a high risk of sudden death is the reentry phenomenon and the authors analyzed its relationship to arrhythmogenic dysplasia of the right ventricle. In a way uncommon in our literature the authors demonstrate the importance of comprehensive electrophysiological examination in these serious cases and its usefulness in confirming the origin of VT in the right ventricle, its importance for mapping the accurate localization of tachycardia and the investigation of effectiveness of drugs and the evaluation of aptness of non-pharmacological treatment.
