Different view and options in custo diagnostic to check the ST-trends. You can view the ST-trends in the following situation:

During the stress test, while recording.
After recording, during evaluation.

At the end of this article you'll find how to setup custo diagnosic.

During the stress

a) Click on Trend

b) Click on ST

The ST-values of the current stage with changes compared to resting stage with changes.

ST-segment can be calculated HR-dependent with a fix value (e.g. j + 60ms, this value can be changed)

c) 2^nd click on ST, the ST-changes are shown graphically

d) 3^nd click on ST: ST-changes compared to resting stage are shown numerically

e) Click on QRS: ST-changes compared to resting stage are shown as ECG

- click on „Resting“ : à Resting ECG is shown

- click on „Zero“ : à baseline (iso-electrical line) is shown

- second click on QRS“ : à second ECG channel can be use for ST-change Monitoring

After recording / during evaluation

a) Click on ST: will show the ST-changes graphically in mV. Each lead can easily chosen or deselected.

b) 2^nd click on ST: ST-Trend will be shown channel-wise and 3rd click switches from chest leads to limb-leads.

d) ST-segment: Table for each Stage.

e) Stage-wise comparison of ST-changes.

f) ST-Measurement overview (all channels all stages)

- right click – opens context menu

Setting up ST visualization

- Here you could select if you want to see a fixed channel for ST or that channel with the highest deviation.

- Do you want to have the ST-values shown in the ECG? If yes check “ST-values” and decide, if you want to have the ST-values only, or with J-point or with ST slope.
