Figure 6 Comparison of intracardiac electrograms between the pulmonary artery (PA) group and the endocardial right ventricular outflow tract (RV-end-OT) group in terms of the amplitude of local ventricular bipolar potentials during sinus rhythm at the successful ablation site. The amplitude in the PA group is significantly lower than that in the RV-end-OT group.
