Fever Exacerbating Ventricular Fibrillation in Early Repolarization Syndrome

Early repolarization (ER) syndrome is characterized by ≥1 mV J-point elevation in 2 contiguous inferior and/or lateral ECG leads in a patient resuscitated from otherwise unexplained VF or polymorphic VT. J-point elevation in these patients may have slurring or notching of the end of the QRS complex. While alterations in temperature have been known to effect other arrhythmia disorders, it has not been described with ER syndrome. We report a patient with ER syndrome which manifest VF after febrile response to severe burns resulting from occupational accident.
