Figure 2 Endocardial unipolar voltage map of the right ventricle using a voltage range from 0 to 5.5 mV is illustrated in the right anterior oblique (RAO) orientation. HeartRhythm Case Reports 2015 1, 82-84DOI: (10.1016/j.hrcr.2015.01.012) Copyright © 2015 Heart Rhythm Society Terms and Conditions

Figure 3 Epciardial bipolar voltage map of the right ventricle (RV) is shown using a voltage range from 0.5 to 1.0 mV. The epicardial RV voltage map identified a low-voltage area in the inferior RV. Fractionated and late potentials were tagged with white, clustering in the RVOT and inferior RV. RFA procedures were applied to eliminate abnormal electrogram areas with good clinical efficacy. RAO = right anterior oblique; RF = radiofrequency; RFA = radiofrequency ablation.
