Position-dependent ventricular tachycardia related to a peripherally inserted central catheter.

Recently, peripherally inserted central venous catheters (PICCs) have been widely used for venous access. Advantages of a PICC over centrally inserted central catheters include the virtual elimination of the risk of pneumothorax, hemothorax, and arterial puncture, along with a reduced risk of bleeding. However, the PICC has associated risks. We present 2 cases of body position-dependent ventricular tachycardia related to PICCs. These events occurred in patients with no prior history of cardiac arrhythmia and were corrected by repositioning of the PICC. They serve to identify a potentially serious cardiac complication of the PICC that, to our knowledge, has not been described previously.
