Background

Peripherally Inserted Central Catheter (PICC) is punctured through the peripheral veins (basilic, median, cephalic), with the catheter tip at the end of the superior vena cava, near the superior vena cava and the deep vein catheterization at the entrance to the right atrium. The PICC catheter head end is arranged in the superior vena cava, so that the occurrence of complications such as infection, thrombosis, catheter occlusion, phlebitis, atrial arrhythmia and the like can be obviously reduced. Therefore, accurate placement of the catheter is an important aspect of clinical PICC placement.

The currently clinically common method for observing the position of the catheter head is a chest X-ray fluoroscopy method, but because doctors and patients are damaged by radiation, the method is not suitable for the placement process of the central venous catheter and can only be applied after the catheterization. In recent years, the position of a catheter is confirmed by using an ultrasonic technology, the method can display images of a large blood vessel, a heart and the catheter, the images are clear, the diagnosis accuracy is high, and the method is lack of practicability due to the complex technology and high price. A large number of research results at home and abroad show that the intracavitary electrocardiogram can continuously record electrocardiogram signals when the central venous catheter is inserted, the catheter is positioned at the junction of the superior vena cava and the right atrium, and the P wave reaches the highest amplitude.
