Muerte súbita en el adulto joven sin cardiopatía demostrable: características clínicas y electrofisiológicas en 3 casos / Sudden cardiac death in 3 young patients without overt heart disease

We reported 3 young adult males who developed spontaneous ventricular fibrillation in the abscence of demonstrable heart disease. Extensive clincial and elelcrophysiilogic evaluation failed to disclose a cause for the arrhythmia. Antiarrhythmic drugs were empirically used in all patients but 2 of then eventually died. Thus, unexplained ventricular fibrillation without demonstrable heart disease carries a serious short term prognosis. An implantable cardiovertodefibrillator may be the therapy of choice in these cases
