CTICasesPacemaker Lead Dislodgment
Imaging findings
Chest radiographs show a newly placed pacemaker. The right atrial appendage lead is hanging straight down within the right atrium without its typical anterior curve, and demonstrates conspicuous blurring on the lateral view due to excessive bouncing/motion.
Key takeaways
Pacemaker lead dislodgment can be recognized on radiographs by the loss of the normal lead contour (e.g., atrial lead pointing downward instead of J-curving into the appendage) and excessive motion blur on the lateral view compared to stable leads.
