Figure 2 Fluoroscopic view (90° right lateral view) of an effective cardiac nerve stimulation site in the SVC. Panel A shows the basket catheter, which was introduced via the right jugular vein, in the SVC. Panel B shows the identical area after injection of 20 ml nonionic contrast medium into the SVC through the jugular vein. Due to the contrast medium, the basket catheter can hardly be seen but it is obvious from Panel A that the catheter was placed just distal to the entrance of the innominate vein from the left but proximal to the entrance of the SVC into the RA. A schematic view of the catheter arrangement and anatomy is shown in panel C. RA = right atrium; SVC = superior vena cava.
