Intra-atrial ECG may fail in select patients; leaves open whether longer catheters improve reliability in elderly males with emphysema.

Why does intra-atrial ECG tracing fail to verify the position of a central venous catheter in certain patients?
Intra-atrial ECG tracing for central venous catheter verification may fail in patients with myocardial pathology or when using standard 20 cm catheters in elderly males with pulmonary emphysema, suggesting longer catheters are needed for these individuals.
Salmela et al. (1993) conducted an observational in Scheduled for central venous catheterization (n=350). Intra-atrial ECG tracing using a 20 cm central venous catheter was evaluated on Failure of intra-atrial ECG tracing. Intra-atrial ECG tracing for checking central venous catheter position failed in 8.3% of patients, often because the 20 cm catheter was too short for elderly males with pulmonary emphysema.
