Plotting Arrhythmia Trend Graphs
When you plot trend graphs the display area consists of:
• a 1.5-second segment of the selected class waveform on the left (individual
class trends only).
• a trend graph of the selected class, or group of classes, on the right. Refer to
Figure 9-2: Abnormal class trend.
When you select CLASS TREND, the trend graph plots occurrences of events
that match that particular class. The total number of events that occurred during
the time period between the cursors appears below the trend graph.
Figure 9-2: Abnormal class trend
When you select GROUP TREND, the trend graph plots occurrences of all events
in that group of classes along with the average heart rate. For example, the group
trend for abnormals plots the occurrences of all single abnormals regardless of
the class in which they were stored.
• The dominant group trend graph displays the total of all abnormal beats,
including beats in runs, over the selected timebase.
• A total of all events specific to the selected class over the selected timebase
is displayed for all other trended classes.
Each trend graph is displayed with two scales:
• the scale on the left represents heart rate.
• the scale on the right displays the number of arrhythmias over the trended
period.
Scales are automatically selected, based on the heart rate and arrhythmia values.
Selecting a Timebase
You can also select the time period over which the system trends arrhythmia data.
The factory default setting is 6-hours. Resolution for each timebase is shown
below.
Resolution Timebase
1-minute = 6-hour trend graph
2-minutes = 12-hour trend graph
4-minutes = 24-hour trend graph
