P lt; 0.05）conclusion：placing PICCcatheter guided by bedside ecg monitoring，can significantly improve PICC catheter tip must be，to avoid the experience method of surfacecatheter length of the forecasting error，easy operation，high accuracy，is expected to become clinical catheter positioning of the specification.【key words】EKG；PICC catheter；Catheter tip to positioning【中图分类号】R540.4+6【文献标识码】A【文章编号】1276-7808（2
