ABSTRACT: We report a case of continuous supraventricular tachycardia in a patient affected by Steinert's myotonic dystrophy. The investigation of this tachycardia showed that there was a "slow-fast" common nodal re-entry, rendered continuous by the existence of significant conduction defects in the fast pathway and the slow anterograde pathway. Implantation of a double chamber cardiac stimulator, necessary for conduction defects present in the basal state in this patient allowed, with the evolution of the conduction defects, the complete eradication of reciprocal rhythm entry, without resorting to ablation.
