In a small study (n = 9) central venous catheters were positioned in front of the right atrium using ECG. ECG was registered using a soft J-wire inside of the catheter. Big vessels were cannulated and in all cases cannulation was successful. ECG and x-ray control showed good agreement.
在一项小型研究（n = 9）中，使用心电图将中心静脉导管置于右心房前方。通过导管内的软J形导丝记录心电图。对大血管进行插管，所有病例插管均成功。心电图和X线检查结果显示高度一致。
