Figure 1

Right ventricular (RV) conduction abnormalities in the index patient. Isochronal maps of sinus rhythm are shown. The maps are orientated in the anterior (A) and posterior (B) views, respectively. The color scale represents timing of activation from onset of the QRS complex (red = early, purple = late). The total RV endocardial activation time was 82 ms, with latest site of activation in the posterior RV (site B). The electrograms in this area are fractionated compared to those in the anterior wall at site A. Similar fractionated electrograms were also identified in the posterolateral RV wall.
