Recording unipolar ECG leads using one limb of the Wilson Central Terminal

Introduction: Since Frank Wilson first proposed “unipolar” surface ECG leads in 1931, the use of the Wilson Central Terminal (WCT) has become the standard electrical reference for the Augmented Limb leads, the Chest Leads and intracardiac catheter electrograms. Wilson's notion of a reference potential at an “infinite” distance providing a zero-volt reference has proved to be mistaken but is a de facto standard. We hypothesized that an equivalent “far field” reference could be obtained by using only one of the limbs of the WCT, enabling the recording of a 12-lead ECG using a single bipolar pair of electrodes.
