The authors registered measurements of ECG via the saline column in a central venous catheter in a prospective investigation. The P-waves in the atrial ECG from various heights in the atrium and low down in the superior vena cava were compared with lead II in surface ECG and this revealed significantly larger P-waves in the invasive ECG. In patients with tachyarrhythmia, who have or require a central venous catheter, the atrial ECG will thus present an alternative to the oesophageal ECG in the diagnostic elucidation. The method is found to be easy to carry out and it is without risks or discomfort for the patient and it provides good information about atrial activity.
作者在一项前瞻性研究中记录了通过中心静脉导管内盐水柱进行的心电图测量。将心房不同高度及上腔静脉下部的心房心电图中的P波与体表心电图的II导联进行比较，结果显示侵入性心电图中的P波明显更大。因此，对于患有或需要中心静脉导管的快速心律失常患者，心房心电图在诊断阐释方面将是食管心电图的一种替代方法。该方法操作简便，对患者无风险或不适，且能提供有关心房活动的良好信息。
