The “Explain” Mode

Figure 10: Diagnostic algorithm reveals findings.

The operator can identify important features that were used to determine a result by activating an “Explanation” pop-up, placing a cursor over the finding. In the above example, there are a number of findings. First, the Acute Septal MI determination is explained. Results can then be confirmed or challenged by examining the underlying tracings at electrodes within the noted regions.

Figure 11: Diagnostic result explained.

Moving the cursor progressively downward explains each successive diagnostic conclusion. Here, an acute inferior and right ventricular MI.

Multiple time-sequenced recordings can be viewed simultaneously in order to identify emerging or resolving conditions.

Figure 14: Side by side images compare findings at diagnosis and post reperfusion.

As many as ten individual images recorded over time can be compared visually and in detail. Deepening and spreading color regions may indicate a worsening condition, whereas the fading of color indicates improvement or resolution. Such images may be used to validate effectiveness of therapy, indicate a need to change therapy, identify regions of involvement or to risk stratify a patient under observation. The recordings in Figure 14 reflect a successful reperfusion.

Cursor placement over an individual electrode location will display the underlying ECG morphology at all time sequences.

This allows immediate comparative analysis both of color images and underlying morphology.
