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

Figure 5 Bipolar and unipolar endocardial right ventricle voltage maps in a patient with ventricular tachycardia in the setting of arrhythmogenic right ventricular cardiomyopathy/dysplasia. A and B: Demonstrate no substantial endocardial substrate on bipolar voltage map; C: Demonstrates a substantial area of unipolar voltage abnormality (< 5.5 mV) encompassing most of the right ventricle free wall in the same patient. AP: Anterior; PA: Posterior.
