title: Use of salt bridge in rhythm analysis.
abstract: Filling a catheter with electrolyte solution converts it to a conductor and allows the safe recording of an electrogram from near or within the right atrium. This technic is very useful in localizing the internal position of a cardiac catheter and particularly in rhythm analysis. Four cases are presented to review the value of this salt bridge technic.
