Selecting an Average Beat for ST Template Generation
To select a rate for the arrhythmia software to generate a new ST template (options are
every 16 beats or every 32 beats):
1. Press ST Config on the Patient Settings screen.
2. Press the ST Alarm button.
3. Toggle the Beat Avg button to select 16 or 32. 32 is the default.
Reference Level For ST Measurement
The ST level can be measured from zero or can be measured relative to the learned ST
template (Lrn). To select the ST reference for the highlighted lead, press the ST
Alarm button then toggle ST Ref to Zero or Lrn. Lrn is the default.
ST Trends
For central arrhythmia source patients, ST level and slope data are trended and avail-
able in the Trend screen.
For bedside arrhythmia source patients, ST level and slope data are trended and made
available if data is available from the bedside monitor.
See “Trend Data” starting on page 159 for further information on trending.
ST Disclosure
ST episode alarms are designated in Full Disclosure (page 147) as medical alarms.
ST History
For central source patients with ST enabled, ST episodes are stored as ST history
events if the alarm is set to STORE on the Alarm Config screen.
Such stored events include:
• 20-second waveforms for up to 7 leads
• current ST templates for each surface ECG lead along with their time stamps
• learned ST templates for each surface ECG lead along with their time stamps
• location of ST measurement points for learned and current templates
For bedside arrhythmia source patients, the ST level and slope data appear in the
Vitals popup and strip or laser printouts if it is available from the bedside monitor.
