Patient
- 76-year-old man
- syncope, complete atrio-ventricular block, atrial fibrillation
- single-chamber pacemaker
- chest X-ray 1 day after implantation
Chest X-ray: antero-posterior view
- right ventricular placed via the left cephalic vein
- the RV lead is directed inferiorly through the right atrium and the tricuspid valve with the tip at the right ventricular apex
Chest X-ray: lateral view (same patient)
- the tip of the right ventricular lead is antero-apical
Now look at the chest X-rays of two other patients with a dual chamber pacemaker.
