(A) A twelve lead electrocardiogram (ECG). Sinus tachycardia with ST depression of inferior leads and ST elevation in I, AVL were observed. (B) A twelve lead ECG. J point elevation in the most of leads and notching of terminal portion of QRS complex were observed. It was prominent, especially in the lateral leads (red arrow). (C) Ventricular fibrillation occurred and it was terminated by defibrillation. After defibrillation, Osborn wave still remained. (D) A twelve lead ECG after infusion of isoproterenol. Early repolarization was nearly normalized. The notch in the lateral leads was noticeably decreased. Heart rate was accelerated by the chronotrophic effect of isoproterenol.
