Figure 3

In the upper panels, Carto V2 (Biosense Webster, Johnson and Johnson) activation maps show the maximum earliness (red zone) of the origin of tachycardia in the right atrium (crista terminalis). In the lower panel, traces during radiofrequency delivery (during AF) with the restoration of sinus rhythm and the appearance of irritative beats identical to tachycardia. In the lower right panel, fluoroscopy during radiofrequency delivery.
