Short axis reconstructions of cardiac FDG-PET acquisition are shown from left to right: in the apex, the mid-ventricular portion and the base of the left ventricle; before (top) and 3 months after right ventricular pacing (bottom). The second FDG scan demonstrated, after right ventricular pacing, a large fixed area of poor FDG uptake in the apex and in the mid inferior, mid-infero-septal and mid-antero-septal segments.
