The correct and dislodged locations of the atrial lead tip are highlighted (blue circles).

Case Discussion

A right atrial lead should show a J-shaped curve on the frontal radiograph (anterior and superior).

It is easy to diagnose a dislodged or misplaced catheter if you have an old study to compare. The cardiologist should be informed that the lead is dislodged.

If no old study is available, then suggest this finding and recommend cardiology evaluation.
