An Early Repolarization Syndrome is a rare clinical entity and is a significant etiology of idiopathic ventricular fibrillation causing sudden cardiac death. We presented a case of a 39 year-old male with no known co-morbidities who had ventricular fibrillation-related cardiac arrest. A 12-lead electrocardiography showed a notched J wave with downsloping ST segment on lead II,III,aVF and V4-V6. Echocardiography showed preserved left ventricular systolic function with no regional wall motion abnormalities, and coronary angiography showed normal coronaries. A Type 2 Early Repolarization Syndrome was diagnosed, and an implantable cardioverter defibrillator was inserted. Early repolarization syndrome is associated with J point elevation, and the more leads involved and a downsloping ST segment pattern as seen in our patient is a predictor of an increase risk for arrhythmogenicity.  In summary, we report a case of a Type 2. Early repolarization syndrome induced idiopathic ventricular fibrillation treated with ICD.
