This study is designed to obtain information for design purposes on use of an ECG guided monitoring system to aid in the correct placement of PICC lines. There is no formal study hypothesis.
PICC line placement is a common procedure, made more difficult by the need to ensure that catheter tip placement is in an acceptable location, typically the superior vena cava (SVC), and ideally at the junction of the SVC and right atrium. Tip location is determined at present by chest X-ray, which is performed after the procedure. If the tip location is incorrect, additional procedures and/or X-rays are needed until proper placement is ensured. Use of an electrode placed inside the catheter during insertion has been reported to provide identifiable changes in the p-wave sufficient to guide placement. This study is designed to collect ECG and catheter depth information during routine PICC placement procedures, and to correlate these ECG changes to tip location as determined by contrast enhanced fluoroscopy.

Distance of Maximum P-wave Amplitude in Relation to Superior Vena Cava (SVC)/Right Atrium(RA) Junction
In order to determine correlation of PICC tip location with the intracatheter ECG, the PICC was advanced at 1cm increments and the p-wave observed for amplitude changes.
Time frame: during catheter insertion
