Full Disclosure Settings. Decide whether the AVSEP Superimposition display and
Arrhythmiagraphs should be displayed and if so, which side of the screen (left or right).
Use the Full Disclosure screen to verify that the analyzer is triggering and classifying the beats
correctly.
Trigger / Triggering: Pathfinder SL displays a yellow arrow underneath a beat to indicate that the
algorithm has seen it. This is called the Trigger arrow. The user should verify the analyzer Trigger
arrow is correct prior to verifying the Events.
Classifying: Beat Annotation and highlight. Pathfinder SL displays the beat classification by
placing a letter under different beat types. (See chapter on Annotation) and by coloring the beat
in different colors.
Verifying that the analyzer has both triggered and classified the beats correctly will ensure that
subsequent Events are also correct. Turn the beat annotation (including trigger arrow and beat
classifications) on/off using the trigger icon.
From the Full Disclosure toolbar, select the ECG channels/leads to be displayed by clicking on

backwards. This feature is also available in the ECG scan screens.
Right Click in the ECG to set the start and end of recording points, this is a useful way to eliminate
artifact from the analysis.
Note:
The analyzer will automatically detect the end point of the valid ECG in the recording. The
operator should check that the detected end point is correct and that there are no un-
analyzed events beyond the detected end point. The operator can manually set the end
point of the recording by right clicking on the ECG and selecting “Set End of Analysis”. The
ECG will then be reanalysed.
