The ECG evolution and Echocardiography during hospitalization. A Sinus rhythm with HR of 74 bpm after VT discontinued. B Sustained VT with HR of 166 bpm when admission. C Enlarged chambers (LVDd 64 mm) and LVEF 28% on echocardiography. D Cardiac remodeling was reversed after the therapy (LVEF 33%, LVDd 60 mm). E Remarkable recovery in last follow-up on echocardiography (LVEF 52%, LVDd 59 mm)
