Figure 3. Electroanatomical bipolar endocardial mapping (left anterior oblique, LAO) and right anterior oblique, RAO) views, Panel A and B) is characterized by normal voltage electrograms in the entire right ventricular chamber. Unipolar electrogram analysis shows however in the anterior aspect of the ventricle/RVOT a narrow area where abnormal electrograms (red; <5.5mV) are recorded; this evidence suggests epicardial substrate abnormalities as an initial stage of the disease, that are confirmed by direct epicardial bipolar mapping (<1.0mV).
