(A) Right anterior oblique view of the right ventricular bipolar voltage map showing a low-amplitude (red indicates <0.5 mV) area in the anteroinfundibular region. (B) Endomyocardial biopsy samples showing fibrofatty replacement (Heidenhain trichrome x40). (C) 12-lead electrocardiogram during clinically-sustained ventricular tachycardia 170 beats/min, with a left bundle branch block/inferior axis morphology.
