Key result
The ECG-ITLS method for PICC positioning in patients with atrial fibrillation achieved 97% correct placement at radiological control, compared to 45.5% using anthropometric measurement.
Why the study?
Current PICC implantation guidelines recommend standard chest X-ray to confirm tip position, and the reliability of the intracavitary ECG method in patients with atrial fibrillation remained to be evaluated.
Does the ECG method improve the correct positioning of PICC catheters in patients with atrial fibrillation compared to anthropometric measurement?
Population
101 patients with atrial fibrillation undergoing PICC placement
Comparison
ECG method (ITLS) vs anthropometric Peres method and standard thoracic chest X-ray

ECG-ITLS may improve PICC accuracy in AF; hypothesis-generating and requires randomized confirmation before practice change.

Does the ECG method improve the correct positioning of PICC catheters in patients with atrial fibrillation compared to anthropometric measurement?
Absolute Event Rate: 97% vs 45.5%
The ECG-ITLS method is highly reliable (97% success) for correct PICC positioning in patients with atrial fibrillation, significantly outperforming anthropometric measurements.
Albertini et al. (2019) conducted an observational in Atrial fibrillation (n=101). Intracavitary tip location system (ITLS) / ECG method vs. Anthropometric measurement (Peres method) was evaluated on Correct positioning of the catheter tip at radiological control. The ECG-ITLS method for PICC positioning in patients with atrial fibrillation achieved 97% correct placement at radiological control, compared to 45.5% using anthropometric measurement.
