[Curative treatment in a patient with exercise induced syncope].
METHODS
A 38 year old man suffered from exercise-induced reproducible dizziness and syncopes.


METHODS
During exercise testing a ventricular tachycardia at a rate of 300 beats/min was identified as the cause of the symptoms. Because of the ventricular morphology with inferior axis, left bunde branch block and the typical monomorphic repetitive characteristics, idiopathic adenosine-sensitive ventricular tachycardia was diagnosed.


METHODS
Curative catheter ablation of the arrhythmogenic focus in the right ventricular outflow tract was performed. The patient has now been free of symptoms for more than two years. The characteristics of idiopathic ventricular tachycardia and the electrophysiological techniques are described.


CONCLUSIONS
Idiopathic ventricular tachycardia is a rare cause of syncope in young patients without underlying heart disease and can be cured by catheter ablation. Exclusion of cardiac diseases, especially arrhythmogenic right ventricular cardiomyopathy, is of prognostic value.
