Figure 7-1. Event recording
After starting the program, press
continuous recording with a speed of 5 mm/s
(configurable). If the unit identifies an arrhythmic
event, it will automatically switch to the fast paper
speed. With the same key
can be stopped. The unit can be set up to
automatically start a trend recording when the
Arrhythmia Mode is initiated.

7 Arrhythmia Mode
7.1 Some Basic Facts
In Arrhythmia Mode, the MAC 1200 continuously
scans the ECG for arrhythmias.
From six simultaneously acquired leads, the MAC
1200 automatically selects the two that provide the
best signal for analysis.
When the analysis algorithm detects an arrhythmia,
the event is recorded with "context" (Figure 7-1).
The length of the recording varies with the duration
of the event episode. In the setup menu (section 9.4
"Arrhythmia Mode") you determine the conditions
for a recording:
− the recorder starts each time it detects a single-
beat event - all
− the recorder starts each time it detects an event
different from the previous event - unequal
− the recorder does not start at all - no.
Some of the system settings can be customized.
They are labeled with "configurable". The following
information refers to a unit with the system defaults
(see table at left). For instructions on changing the
system setup, refer to section 9.4 "Arrhythmia
Mode".
