Messages indicating disconnected electrodes
Note
- With copy , a single-page recording can be initiated
after program start.
- Please note that filters may suppress diagnostically
relevant portions of the signal, because they
limit the transmission range.
Filters should therefore only be enabled if necessary.
- For proper functioning of the ECG analysis algorithm,
pacemaker patients must be identified
in the patient data: Pacemaker – Yes (section 4.4
"Entering Patient Data").
− After switching on the unit, press
the Arrhythmia Mode.

− Before recording the ECG, patient data can be
pat
entered (
info
). We recommend to enter the patient's
name to annotate it on each page.
− Before initiating a recording, check the display
for error messages (see table at left). Check all
electrodes; if the message persists, there must be
a break in the patient cable. Replace the cable
with a new one.
− The recording is started and stopped with the
key.
Upon program start, 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". Having completed the learn phase, the
MAC 1200 is ready to identify arrhythmias.
With the system defaults, the MAC 1200 will activate
the following functions and settings:
− the STD_C report sequence V1 through V6
(configurable)
− a 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)
− the AC filter is enabled (configurable)
− the muscle filter is disabled (configurable)
