Due to the complications associated with the incorrect placement of a central venous pressure (cvp) catheter, the correct positioning of a cvp catheter must be controlled. The widespread standard in many hospitals is to carry out a chest x-ray (cxr) following the infusion of a contrast medium through the catheter tip. Together with a recent publication and our experience we would like to introduce a method, which is presently not in widespread use, which enables the exact localization of a catheter tip under ECG control. This technique is simple to apply, reliable and time saving. Furthermore it costs only 20% of the amount required for a radiologically controlled catheter placement. Important for ECG-guided catheter placement control is the availability of an ECG monitor suited for intracardial application and the patients heart rate must be in sinus rhythm.
由于中心静脉压（CVP）导管放置不当会引发并发症，因此必须控制CVP导管的正确定位。许多医院普遍的标准做法是在通过导管尖端注入造影剂后进行胸部X光检查（CXR）。结合最近的一篇文献以及我们的经验，我们想介绍一种目前尚未广泛使用的方法，该方法能够在心电图控制下准确确定导管尖端的位置。这项技术操作简单、可靠且节省时间。此外，它的成本仅为放射学控制导管放置所需费用的20%。对于心电图引导下的导管放置控制而言，重要的是要有适用于心内应用的心电图监测仪，并且患者的心率必须处于窦性心律。
