Syncope in a school athlete

We present the case of a 10-year-old girl who suffered syncope during the effort, who was diagnosed with catecholaminergic polymorphic ventricular tachycardia. It is an arrhythmogenic channelopathy that can trigger severe ventricular arrhythmias and has a high risk of sudden death in young patients witch normal heart structure. Syncope is a common medical problem, with an estimated prevalence of 40% in the general population. It usually has a benign course, although 2-3% can also be related to cardiac events and be a symptom of possibility of sudden death. The anamnesis is essential to identify the causes and trigger mechanisms and guide the diagnostic tests to be performed. In this case, the ergometry was the diagnostic test, since it showed the arrhythmia. The decision about the sport aptitude will be individualized and will depend on the aetiology of the syncope. The prognosis should be established and the possibility of recurrences and sudden death should be assessed and the misdiagnosis of both contraindication and sports aptitude should be avoided.
