Key result
A chest radiograph identified excess atrial and ventricular lead slack causing lead-lead interaction and artifacts, which resulted in frequent short episodes of inappropriate mode switching.
Case Report (n=1)
Chest radiography can be a simple and effective tool to identify lead-lead interaction as a cause of inappropriate mode switching in patients with dual-chamber pacemakers.

May warrant chest radiography for unexplained mode switching in dual-chamber pacemakers; leaves open prospective validation.
Marino et al. (2015) conducted a case report in Inappropriate mode switching (n=1). Chest radiograph was evaluated on Identification of the cause of inappropriate mode switching. A chest radiograph identified excess atrial and ventricular lead slack causing lead-lead interaction and artifacts, which resulted in frequent short episodes of inappropriate mode switching.
