Figure 2 A posterioanterior chest radiograph that was obtained following the implantation of a dual-chamber implantable cardioverter-defibrillator in the right chest. The vagal nerve stimulator is seen in the left subpectoral area with a thin lead (red arrows) traversing up to the left vagal nerve in the neck to which is it is attached.
