Critical Events: It’s Not Just a Newsletter!

One of the Clear Technical Advantages (CTAs) that NEMon users have is the Critical Events tabulation. We hear from our user community regularly that this is one of the most useful features they have seen and the first step they make in the process of producing a complete Holter study.

The Critical Events table is a feature in all levels of Holter LX Analysis software except BASIC. Think of it as the “table of contents” for your Holter study. With one quick look at that primary screen display after analyzing the Holter data, users can often quickly tell if the study needs further refinement or if the study has already adequately provided the necessary diagnostic clues.

Here is a screen shot showing the Critical Events table in the upper left-hand spot. In it, you can see the category names and the number of beats that fell into that Critical Event category.

This Critical Events view of the information is so important that many users designate it as the default screen to be viewed upon completion of each analysis run. To set that preference, go to File > Preferences and see the drop down list to the right-hand side of After analysis show. See the next screen shot with the Critical Events selection highlighted as the third option in the drop-down list.

So what are the categories into which the beats are sorted in the Critical Events table? Great question — and here is the list of categories:

VPB SVT Diary or event
Early VPB Aberrant SVPB Irregular RR
VTAC ST event Questionable
Bigeminy Pause HR strips
Trigeminy V. paced Saved strips
Quadrigeminy A. paced Artifact
R on T AV. paced Normal
SVPB Sense failure All
SVPB pair Inhibition

Having the beats automatically grouped into these categories is an enormous time-saver and a great point from which to launch your work on a Holter study. In short, Critical Events may be a smart place to begin your work.
