ST measurements can only be displayed when the full arrhythmia and ST option is
licensed, and when ST is enabled in setup parameters (See “Defining parameter
fields” on page 25).
Note
When the monitor is connected to the Acuity Central Station, ST support is
provided by Acuity and the ST option is not displayed on the monitor.

is set at 60 ms.
