title: A good excuse for skipping the test: electrical storm in a teenager.
abstract: We describe the case of a teenager with a structurally normal heart that presented withtorsades de pointesand cardiac arrest. He had a history of epilepsy in childhood, mild cognitive impairment and cognitive visual dysfunction. The baseline electrocardiogram had prominent J waves and a marked early repolarization pattern in all the leads, with normal QT interval. We discuss the differential diagnosis for this interesting case, as well as the patient's management.
