Does hypothermia trigger ventricular fibrillation in patients with early repolarization syndrome?
Hypothermia can act as an environmental trigger for ventricular fibrillation in patients with early repolarization syndrome.
Hypothermia may warrant caution in early repolarization syndrome; hypothesis-generating case leaves open need for prospective confirmation.
INTRODUCTION: The early repolarization (ER) pattern on ECG was originally described in the context of hypothermia. CASE SUMMARY: We present the case of a 34-year-old male with cardiac arrest in the context of spontaneous hypothalamic mediated thermal dysregulation after intracranial hemorrhage. Ventricular fibrillation with a marked ER pattern recurred with therapeutic hypothermia. Spontaneous hypothermia due to hypothalamic dysregulation was observed to enhance the amplitude of the ER pattern and was contemporaneous with recurrent ventricular fibrillation during follow-up. CONCLUSIONS: Hypothermia is an important trigger of VF in the setting of early repolarization syndrome, and warrants assessment as an environmental trigger of spontaneous events.

FEDERMAN et al. (2012) conducted a case report in Early repolarization syndrome and ventricular fibrillation (n=1). Spontaneous hypothermia was evaluated on Ventricular fibrillation. Spontaneous hypothermia triggered recurrent ventricular fibrillation and enhanced the amplitude of the early repolarization pattern in a 34-year-old male with early repolarization syndrome.
