To include the channel right-click in the graph and select “Enable ST for this channel”.
In the ST Action replay panel are a number of markers, these indicate the measurement points
for the ST analysis.
The operator can adjust the position of the following markers:
Ref:
Drag this to place the cursor at the isoelectric level.
J
: Drag this to place the J point on the ECG.
DMP:
Drag this to adjust the DMP (Deviation Measurement Point) with respect to the J
marker.
The SRP (Slope reference point) marker is fixed relative to the J point,and is automatically
positioned according to the ST Analysis settings. As you move the J marker the SRP and DMP
measurement points will move accordingly.
On the right are the ST Graphs from top to bottom they show the measurements for Channel 1
to 2 to 3 and the corresponding heart rate shown as beats per minute along the bottom. Once
the markers have been set periods of ST deviation (depression and elevation) and shown in red
on these graphs.
19.2 ST Action Replay Display
The ST Action Replay Display allows the operator to playback the ECG in a superimposition
mode so they make more accurately place the ST measurement points for different parts of the
recording. This allows the analysis to cope with natural drift in the timing of the ST segment.
Click on the ST graph and click the play button or select a period of ST from the ST graphs and
select “Action Replay”. The ECG is then animated in an averaged beat superimposition display.
The animation speed can be adjusted or paused.
The ST markers can be adjusted by clicking on the marker label
and dragging it.
From the buttons underneath this ECG the operator can decide
to apply the adjusted markers:
All:
This will set the markers for the entire recording
Selected Area:
This will apply the markers to only the area
selected from the graph
Rest of ECG: This will apply the change from this point forward.
Use these options to review the ECG and ensure the markers
are correct throughout. Based on these and the ST Analysis
settings Pathfinder SL will create ST Events for review.
