Wilson Central Terminal ECG Database

The Wilson Central Terminal ECG Database (WCTECGdb) contains the Wilson Central Terminal (WCT), the voltage of right arm (RA), left arm (LA) and left leg (LL), six unipolar chest leads associated with three limb leads and six precordial leads.

With our ECG device, the potentials of RA, LA, LL and six true unipolar leads are measured using the right leg as the reference point. Having this configuration, we have been able to overcome the difficulty of recording the WCT in a clinical setting. Our data confirmed once again that the WCT does not have a small value, and could be as high as 241% of lead II and has standard ECG characteristics such as the p-wave and the t-wave. The dataset comprises of 540 ten-second segments recorded from 92 patients.

威尔逊中央终端心电图数据库（WCTECGdb）收录了威尔逊中央终端（WCT）、右上肢（RA）、左上肢（LA）及左下肢（LL）的电压，以及与肢体导联相伴随的六个单极胸导联。借助我们的心电图设备，以右下肢为参考点，测量了RA、LA、LL及六个真正的单极导联的电位。凭借此种配置，我们得以克服在临床环境中记录WCT的困难。我们的数据再次证实，WCT并非微不足道，其数值可高达II导联的241%，并具备标准心电图特征，如P波和T波。该数据集由来自92名患者的540个十秒记录片段组成。
