[Ventricular repolarisation disorders and long QT syndrome: clinical and genetic study in 10 paediatric cases].
We report 10 paediatric cases of ventricular repolarisation disorders and long QT syndrome, which differed in their mode of revelation, from asymptomatic forms to syncope events or heart arrest. Diagnosis is based on electrophysiological explorations and exhaustive genetic investigation. It allows a well-codified preventive and therapeutic action according to the genotype.
