Effect of Reference Electrode on Intracardiac Electrograms: Close Indifferent Electrode vs. Wilson Central Terminal

Unipolar electrograms (Uni-EGM) are an essential part of intracardiac mapping. Although Wilson Central Terminal (WCT) is conventionally used as a reference for signals, avoiding contamination by far-field and non-physiological signals is challenging.
