RR/NN Interval Events
The analyser will determine the the Longest and Shortest RR and NN Intervals from the
recording. RR intervals include any interval, NN intervals are only between N beats also excluding
intervals within a period of AF. During editing of these events, selecting the Reject Button will
automatically find the next longest or shortest event for confirmation or printing.
These events can be switched off in the event definitions menu if not required. They will then be
also removed from the report.
Peak Rate Detection Settings:
This setting applies to all event families except max/min heart rate events and AF which have
separate configurable peak detection rate settings. There are three options to choose from:
• 10s average (based on a 10 second rolling mean)
• Event Average of the whole event
Peak Interval pair (based on the average of the fastest pair of consecutive intervals. This is the
default setting)
4.6 Analysis Menu
The Analysis option on the menu bar allows the operator to re-start and change some analysis
settings.
Save Analysis:
At any point in the analysis the operator can save their work and close the analyzer to resume
analysis later.
From the Analysis Menu option select Exit or click on the red X in the top right corner of the
screen. A dialogue will prompt the operator to select ‘Save’ to store any analysis completed so
far. Pathfinder SL will close taking the operator back to Sentinel.
To resume analysis from the Holter Test Screen click on a test, then select “Resume Analysis, and
if there are multiple analyses for that test, select the analysis that you would like to resume from
the “created” list.
Restart Analysis:
The Operator can re-start the analysis from the very beginning. All edits and printed events will
be removed from the analysis. This option allows the user to set which ECG channels are used to
analyze the recording.
Re-Do Analysis With My Edits
Note:
Use this operation with care as it will cause the analysis to re-run from the beginning
although edited classifications & events are kept.
This operation is designed for cases where the automatic analysis does not identify the
Normal QRS shape from the start of the recording. Typically this may happen due to noise or
unusual amounts of arrhythmia. This feature takes the operator edits (both reclassification and
confirmations) to teach the analyzer the major QRS / Ventricular shapes.
To use this feature the operator
must have confirmed and reclassified
at least 5 minutes
into the recording and also identified the Ventricular & Normal QRS shapes. If the analyzer does
not see any user edits it will not perform the operation.
