Einthoven unipolar leads include the potential of the right arm, left arm, and left leg which, by definition, are used to form the Wilson central terminal (WCT) as the average of these three limbs leads. In a traditional 12-lead ECG system, it is not possible to measure WCT directly. It is assumed to both be steady during the cardiac cycle with the assumed value most commonly being-2/3 of the augmented vector foot (aVF) lead. Using our novel ECG device that records Einthoven unipolar leads in addition to traditional 12-lead ECG signals, we investigate whether the WCT and aVF are proportional and the WCT can accurately be replaced by-2/3 of the aVF lead. We use the Einthoven unipolar leads features to evaluate both of the assumptions in regards to the WCT amplitude and value.

Abstract
Einthoven unipolar leads include the potential of the right arm, left arm, and left leg which, by definition, are used to form the Wilson central terminal (WCT) as the average of these three limbs leads. In a traditional 12-lead ECG system, it is not possible to measure WCT directly. It is assumed to both be steady during the cardiac cycle with the assumed value most commonly being-2/3 of the augmented vector foot (aVF) lead. Using our novel ECG device that records Einthoven unipolar leads in addition to traditional 12-lead ECG signals, we investigate whether the WCT and aVF are proportional and the WCT can accurately be replaced by-2/3 of the aVF lead. We use the Einthoven unipolar leads features to evaluate both of the assumptions in regards to the WCT amplitude and value.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
