Atrial fibrillation induced by peripherally inserted central catheters.

Peripherally inserted central catheters (PICCs), a form of central venous catheter (CVC) inserted into the cephalic or basilic veins, are most commonly used for administration of long-term antibiotics or for total parenteral nutrition. PICCs are associated with fewer complications than traditional CVCs; however, they have been implicated in accidental malpositioning, leading to both atrial and ventricular arrhythmias. We present a case of atrial fibrillation possibly triggered by migration of the tip of the PICC deep into the right atrium. Retraction of the tip resulted in resolution of the arrhythmia.
