Transthoracic echocardiography as bedside technique to verify tip location of central venous catheters in patients with atrial arrhythmia.

Tip location of central venous catheter by transthoracic echocardiography with bubble test is feasible, safe, and accurate in patients with atrial arrhythmia. This method can also be applied in peripherally inserted central catheters; however, further studies may be needed to confirm its use in this type of catheters.
