The lateral chest X-ray film obtained just after pacemaker implantation demonstrated that the tip of the lead was in the correct position (Figure 1(a)) and the pacemaker threshold was normal. A lateral chest radiograph obtained on the same day demonstrated displacement of the pacemaker lead (Figure 1(b)).
Chest CT reveals perforation of the right ventricle by the lead.
