Early repolarization syndrome ( ERS ) was originally considered a normal variant with benign outcome. However, recent studies have demonstrated that it can be linked to a considerable risk of life‐threatening arrhythmias and sudden cardiac death. We report a case with an extraordinary, extremely malignant clinical expression of ERS refractory to all antiarrhythmic drugs including quinidine. This case demonstrates real‐time changes of dynamic electrocardiogram ( ECG ) preceding a polymorphic ventricular tachycardia ( VT )‐ventricular fibrillation ( VF ) and possible external factors triggering arrhythmia onset. Implantable cardioverter‐defibrillator ( ICD ) function was terminated 6 months after implantation due to multiple‐incessant electrical storm ( ES ). Catheter ablation was the definite treatment of this malignant entity.
