Intended Use and Functional Description

1 Intended Use and Functional Description
The MAC 1200 is an ECG acquisition and recording
system designed and manufactured by Marquette
Medical Systems.
−It is intended to be used for resting ECG
recording and realtime ECG recording with or
without arrhythmia detection.
−It is not intended for use as a vital signs
physiological monitor.
−The arrhythmia detection portion of the MAC
1200 is provided to the customer for the
convenience of automatic documentation. It is
not designed to provide alarms for arrhythmia
detection.
−The MAC 1200 offers no diagnostic opinion to
the user. Instead it provides analytical statements
when configured with the appropriate options.
−It is intended to be used by trained operators
under direct physician supervision when ECG
records are required.
−It is suitable for intracardiac application.
−It is designed for continuous operation.
−It is not intended for home use.
−The MAC 1200 is designed as a portable device
and can easily be moved from one patient to
another or to different locations. It is not intended
to be used during patient transport.
Equipped with the standard software, the MAC 1200
supports the following operating modes:
−12 Lead Mode (acquisition of 12 leads of ECG
for a period of 10 seconds) and
−6 Lead Mode (real-time recording of 6 ECG leads
−Arrhythmia Mode (continuous ECG analysis for
arrhythmias).
The graphics display shows 3 leads at a time.
Resting ECGs can be transferred to the MUSE CV
Information System via the RS232 interface.
The device operates from both AC and DC
(rechargeable batteries) power sources.
The unit's performance features can be upgraded
with the following optional programs:
−MEAS - measurement (measurement of the 10-
second resting ECG)
−DIAG - interpretation (interpretation of the 10-
second resting ECG)
−MEMO - memory (storage of a maximum of 40
10-second resting ECGs)
-C100 - activates the three options MEAS, DIAG,
MEMO for a maximum of 100 ECGs
-C500 - activates the three options MEAS, DIAG,
MEMO for a maximum of 500 ECGs
-EVAL - activates the three options MEAS,
DIAG, MEMO for a maximum of 4 weeks
The electrocardiograph has a setup menu to
customize the system parameters.
Patient and user data can be entered for reliable and
safe archiving of patient records. The patient name is
annotated on each printed report page. All other data
are printed on request.
