Abstract

An apparatus, system and method for visually determining a physiological signal threshold are capable of providing a graphical user interface (GUI) useful for determining an electrocardiogram threshold parameter. The apparatus includes a physiological signal monitor, a display and a processor. The processor coupled to the display and is configured to receive, from a patient, at least one physiological signal and generate a graphical user interface (GUI) in the display. The GUI includes a first display portion configured to display a subset of the at least one physiological signal and to display a threshold parameter of the at least one physiological signal. The threshold parameter is displayed in the GUI superimposed on the subset of the at least one physiological signal.
