Potential recorded by the which of the following is considered to remain relatively constant during the cardiac cycle
[A] V1
[B] aVR
[C] I + II
[D] Wilson Central Terminal
Wilson’s Central Terminal
Wilson’s Central Terminal
Wilson’s Central Terminal (WCT) is an artificially constructed virtual reference potential for surface electrocardiography (ECG). It is derived by averaging the voltage of the right arm (ΦR), left arm (ΦL), and left leg (ΦF), and is assumed to be steady and with negligible amplitude during the cardiac cycle.
