[Kearns-Sayre syndrome: complete auriculoventricular block, torsade de pointes and ventricular fibrillation].
The authors present the case of a new case of Kearns-Sayre syndrome, with early manifestations (7 months) and dramatic cardiac course. They document the ultimate and often fatal stage of the cardiac disorders of this syndrome, which was usually related to an asystole due to a total atrio-ventricular block and represented in this case by a ventricular hyperexcitability (ventricular tachycardia--"torsade de pointes"--ventricular fibrillation) occurring on an atrio-ventricular block; only one previous, undocumented case was found in the literature. The literature is reviewed in order to analyze the nature and chronology of the heart disorders in the course of the disease, and stress the screening modalities and therapeutic indications (continuous heart stimulation).
