Purpose: This study analyzed the value of an electrocardiogram (ECG) using an arterial pulsator in central vein catheterization (CVC). Methods: In 442 patients who underwent CVC with an ECG and an arterial pulsator, this study evaluated the rates of change in the P wave and the QRS wave at the limb lead II before and after insertion. After insertion, a plain chest X-ray was checked in order to locate the catheter tip. Results: After catheterization, the P wave and the QRS wave increased together at 97% but the P wave (change rate: 0.5∼21.0) was more sensitive than the QRS wave (change rate: 0.5∼5.8). For an abnormal location (3%), the rate of change in the P wave was ＜2.0 and that of the QRS wave was ＜1.4. The sensitivity and the specificity of the P wave ＞2.0 were 95% and 100%, and those of the QRS wave ＞1.4 were 90% and 100%. Conclusion: In central vein catheterization, an electrocardiogram with an arterial pulsator can be a useful method, and the normal position of the catheter tip can be estimated by using a rate of change in the P wave ＞2.0 or a rate of change in QRS wave ＞1.4.
