case_images: Initial 12-lead electrocardiogram revealed sinus rhythm with notched type J wave and >0.1 mV ST-segment elevation at inferior leads.

case_images: The initial ECG (Figure 1) showed sinus rhythm and a normal QTc interval of 431 ms with notched type J wave and ST-segment elevation in leads II, III, and aVF.
case_images: Electrocardiogram during peak treadmill test showed wide QRS-complex tachycardia, suggesting ventricular tachycardia.

case_images: Analysis of the ECG (Figure 2) highlighted a wide QRS-complex tachycardia episode that lasted less than 1 minute and terminated spontaneously; afterward, no ST-segment changes occurred.
case_images: Electrocardiogram after implantable cardioverter defibrillation implantation showed persisting early repolarization patterns in the inferior leads similar to the initial examination accompanied with bigeminy premature ventricular complex.

case_images: Postprocedural ECG (Figure 3) showed a persisting ER pattern, similarly to the initial ECG, with frequent premature ventricular complexes that may serve as trigger for VA.
