The ST/HR view plots the ST segment depression against the heart rate. You can display this
graph for each lead. In the left hand pane, the ST/HR index is shown. More information can
be found in Okin PM, Kligfield P (1989), Computer-based implementation of the ST-
segment/heart rate slope, American Journal of Cardiology.
You can select to show the exercise phase, the recovery phase or both by checking the
option from the checkbox above the graph.

Click on a lead in the left hand pane or select the lead from the drop down box.
To invert the ST/HR curve:
Click on the graph with your right mouse button and select Invert from the shortcut
menu. Click once more to flip the graph back to its original position.
