Key result
A 52-year-old man with a type 2 early repolarization pattern and no structural heart disease presented with ventricular fibrillation and was successfully treated with an implantable cardioverter defibrillator.

This case report highlights the potential association between a type 2 early repolarization pattern in inferior leads and life-threatening ventricular fibrillation in a patient without structural heart disease.
Type 2 early repolarization may link to VF without structural disease; single case leaves open risk stratification.
An early repolarization (ER) pattern, characterized by J-point elevation, slurring of the terminal part of the QRS and ST-segment elevation, is a common finding on the 12-lead electrocardiogram. It has been suggested that J-point elevation, which was considered benign for many years, may play a critical role in the pathogenesis of idiopathic ventricular fibrillation (VF). Recent studies have shown that an ER pattern in inferior leads or inferolateral leads is associated with increased risk for life-threatening arrhythmias. We report the case of a 52-year-old man with no structural heart disease whose electrocardiogram showed type 2 ER pattern (with evidence of J-point and ST-segment elevation in electrocardiogram leads II, III, and aVF). The patient presented with VF.

Yavuzer Koza (2014) conducted a case report in Early repolarization syndrome with ventricular fibrillation (n=1). Implantable cardioverter defibrillator (ICD) was evaluated. A 52-year-old man with a type 2 early repolarization pattern and no structural heart disease presented with ventricular fibrillation and was successfully treated with an implantable cardioverter defibrillator.
