Popis: Abstract Purpose To explore the application of ECG‐guided localization technology in PICC catheterization and the clinical significance of different maps of intracavitary ECG in PICC tip localization. Methods In the process of catheter placement under the guidance of ultrasound, the technique of intracavitary ECG location was used. The length of the catheter was measured on the body's surface. The amplitude of the P‐wave and the QRS‐wave groups of electrocardiograms before and during catheter placement was recorded. Nine hundred sixty‐one patients who underwent X‐ray chest film examination after catheterization were imaged on the chest film at the tip of the catheter. Results Eight hundred four cases had a characteristic P wave, 83.66%, of which, 331 cases (50% < P/R ≤80%) had 99.09%; 425 cases (80% < P/R ≤100%) had 99.29%; 48 cases (P/R >100%) had 100%. One hundred eighteen cases of non‐specific P wave accounted for 12.28% and 79.66% of chest radiographs, of which 72 cases of P/R
