[A case of severe catecholaminergic bitachycardia].
The authors report the electrophysiological study of severe catecholaminergic double tachycardia in a young athletic subject with an apparently healthy heart. The literature is reviewed and the mechanisms of double tachycardia are discussed, together with the role of the sympathetic nervous system and the therapeutic implications.
