Sudden death caused by cardiac sarcoidosis in childhood.

This report describes an adolescent who presented with ventricular tachycardia (VT) originating from the right ventricular apex, with no apparent underlying cause. Cardiac sarcoidosis was identified only at postmortem examination after sudden death. There must be a high index of suspicion for subtle forms of primary myocardial abnormalities in such cases. Investigation for VT should include specific investigations for cardiac sarcoidosis when no other pathology has been identified and there are persistent conduction abnormalities on resting ECG.
