Image finding: Value of lateral views


Lateral radiograph


The PA (postero-anterior) radiograph at first appears to provide reassuring evidence that the tip of the pacemaker lies in the right ventricular apex. The slightly thickened metal tip of the pacemaker is seen just lateral to the border of the descending aorta near the diaphragm. The value of a lateral radiograph is best exemplified (click the "Lateral X-ray"button located on the right side of the main screen) when the course of the pacemaker wire is followed inferior and is found to lie well posterior to the expected position of the right ventricular cavity.
