ECG Alarm Messages
The following messages apply when either the 91341, 91343, or 91347 is in use.
CHECK XX
Displayed in the waveform zone, where XX is the name of the faulted electrode.
The message clears after 60 seconds for V1 – V6 and RL. It is not cleared for limb
lead (RA, LA, LL) faults. If multiple electrodes have faulted, only the highest
priority fault is displayed. The limb leads are highest, followed by RL, followed by
the Vx leads.
ABNORMAL/MINUTE ALARM
Displayed whenever the abnormal in minute count (A=XX) initially exceeds the
ABN IN MIN alarm setting. This message is displayed for 10 seconds.
ASYSTOLE
Displayed whenever no beat is detected for 5 seconds. This message is displayed
for the greater of 10 seconds or the duration of the alarm.
COUPLET ALARM
Displayed whenever a couplet is detected and the ABN IN ROW alarm limit is ON
and set to 2. This message is displayed for 10 seconds.
ECG ALARMS OFF
Displayed in reverse video whenever ECG alarms are OFF.
ECG ALARMS SUSPENDED
Displayed in reverse video whenever alarms have been suspended with the
monitor’s TONE RESET/ALM SUSPEND hard key.
ECG PROCESSING SUSPENDED
Appears whenever ECG and arrhythmia processing have been suspended with
the SUSPEND PROCESSING key and menu. This message is displayed until
processing is resumed.
ECG VOLTAGE TOO LOW
Displayed whenever the ECG signal is below the detection threshold. This
message only applies to ADULT mode for QRS amplitudes in the range of 160 µV
to 200 µV. After 10 seconds in this condition, an alarm tone sounds if ECG alarms
are enabled and alarm tones have not been turned OFF or suspended.
HI RATE ALARM
Displayed during high rate alarms for the greater of 10 seconds or for the duration
of the alarm.
IN LEARN
Displayed when the module is in learning mode.
CHAN 1 & 2 LEADS OFF
Displayed when lead failures preclude ECG monitoring in both ECG channels 1
and 2. The message in displayed in the waveform zone for the first ECG channel.
An alarm tone sounds if the module has completed its initial period of learning and
ECG processing has not been suspended.
