Arrhythmias and ischemia-like ECG changes in Reye's syndrome.

We report a fatal case of a child presenting Reye's syndrome associated with a variety of arrhythmias and ischemia-like ST-T ECG changes. At autopsy, fatty infiltration and patchy myocytolysis were detected in sections of the heart. This case report emphasizes cardiac involvement in Reye's syndrome and the possible mechanisms of arrhythmias in this disease.
