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.
