Research Progress of Intracardiac Electrogram Localization Technology in PICC Tip Localization

As a safe, accurate and radiation-free method of catheter tip positioning, intracardiac electrogram positioning technology (IC-ECG) has shown significant advantages in the field of peripherally inserted central catheter (PICC), and has been increasingly concerned and welcomed by clinical operators at home and abroad in recent years. This article reviews the technical principle, clinical progress, advantages and limitations of IC-ECG, aiming to provide a reference for further clinical research and application of this technology.
