[Transluminal electric catheter ablation in the treatment of drug-refractory focal ventricular tachycardias].

In a 46-year-old patient with dilatative cardiomyopathy and medicamentously therapy-resistant focal ventricular tachycardias after endocardial right- and left-ventricular catheter mapping a transvasal electric ablation of the focus of tachycardia was carried out. For this purpose at the left-ventricular-septally localized origin of tachycardia two electroshocks of 100 and 200 J via the electrode catheter positioned there was given. Immediately after ablation a stable sinus rhythm was to be registered; longer persisting recidivations of tachycardia did not appear again subsequently. In the further course the patient suddenly died after transitory haemodynamic improvement, in which case a new, acutely beginning arrhythmia is to be assumed as a prefinal event.
