Arrhythmia Mode Recording: Recording
During the Recording
When the program starts, the unit records 6 leads of ECG (1 page).
During the following learn phase, the analysis algorithm learns the
patient’s typical QRS complex.
After the learn phase, the recorder prints a report where the QRS
complexes acquired in the learn phase are labeled L and the complex
found to be the patient’s typical complex is labeled QRSL.
When the learn phase is complete, the MAC 1200/1200 ST is ready to
identify arrhythmias.

With a single-page recording can be initiated after program

Filters may suppress diagnostically relevant portions of the
signal, because they limit the transmission range. Only enable
filters if necessary.
With the system defaults, the MAC 1200/1200 ST will activate the
following functions and settings.
„ STD_C report sequence (lead to channel correspondence) (V1 to V6)
(configurable).
„
Gain of 10 mm/mV (configurable) (calibration pulse at the beginning
of the recording). The unit can be set up to automatically adapt the
gain to the ECG signal (*auto).
„ Muscle filter is disabled (configurable).
„
AC line filter is enabled (configurable).
„ Slow trend recording is disabled (configurable).
„
Event episodes are recorded at a speed of 25 mm/s.
„ Unit documents all events that are different from the previous event
(configurable). The unit can be configured to document all events or no
events at all.
„
In the final report, the event episodes are printed in chronological
order.
