[Sudden unexpected nocturnal death: report of a case and review of the literature].
Sudden death usually affects individuals with severe heart disease. A more dramatic phenomenon is the sudden unexpected death of individuals with no evidence of heart disease. It has been described mainly in young healthy males under severe stress. We present a 32 year old man who presented ventricular fibrillation during sleep and was resuscitated by his wife. Recurrent episodes of VF occurred in the following hours. The study, including coronary angiography, revealed a normal heart. Endomyocardial biopsy showed minimal alterations with scarce areas of atrophy and fibrosis. Electrophysiologic evaluation showed an extremely short refractory period of the right ventricle, but the arrhythmia could not be induced by electrical stimulation. An internal cardioverter defibrillator was implanted since the risk of recurrent VF was high. A review of the literature concerning this unusual entity is offered.
