Ventricular tachycardia mapping and ablation in arrhythmogenic right ventricular cardiomyopathy/dysplasia: Lessons Learned

Figure 3 Epicardial right ventricle bipolar voltage map and isolated late potentials in sinus rhythm. A: Demonstrates significant epicardial bipolar voltage abnormalities (< 1.0 mV) over the right ventricle free wall. The black tags on the electroanatomical map represent areas of abnormal fractionated and/or late signals identified during sinus rhythm voltage mapping; B: Provides an example, as exhibited by the white arrows, of an isolated late potential. AP: Anterior.
