Figure 4 (a and b): X-ray Contrast Images Before and After Pacemaker
Extraction
The two X-rays above show the contrast images taken before and after
pacemaker extraction. The left image (Figure 4a) displays two pacemaker
generators positioned below the bilateral clavicles. The pacemaker on
the right side is a 15-year-old single-chamber pacemaker, with its
electrode lead located at the right ventricular apex. The pacemaker on
the left side is a one-week-old dual-chamber pacemaker with pacing
electrodes situated in the right atrial appendage and the proximal
septum. The right image (Figure 4b) shows the single-chamber pacemaker
generator extraction with the passive electrode remaining in place.
