Catecholaminergic polymorphic ventricular tachycardia in children. El electrocardiograma en reposo es normal excepto por casos aislados de bradicardia sinusal. The diagnosis is confirmed by inducting ventricular tachycardia through a stress test or during an infusion of sympathicomimetic drugs like Isoproterenol, aided by the identification of mutations in the RyR2 and CASQ2 genes through gene analysis.

Mutations in the Ryanodine receptor gene RyR2, have been linked with an autosomic dominant form, while mutations in the Calsequestrin gene CASQ 2 have showed correlation with an autosomic recessive form.
