Case 2: Chest radiograph following permanent pacemaker insertion shows a pulse generator implanted in the left infraclavicular area. Two leads track through the subclavian vein into the superior vena cava. The atrial lead loops upwards and anteriorly in the right atrium and is fixed in the right atrial appendage (black arrow). The ventricular lead crosses the tricuspid valve and is fixed at the right ventricular apex (white arrow).
