Effect of reference electrode on intracardiac electrograms: Close indifferent electrode vs Wilson central terminal

Unipolar electrograms (uni-EGMs) are an essential part of intracardiac mapping. Although Wilson central terminal (WCT) is conventionally used as a reference for signals, avoidance of contamination by far-field and nonphysiologic signals is challenging.
