8-4
The ECG function:
• detects and displays a waveform representing each cardiac cycle
• determines lead configuration options
• displays heart rate (heart rate is computed from an average of eight beats
with a provision for immediately updating the heart rate should the rate slow
suddenly)
• detects pacemaker pulses
• initiates ECG-related alarms when limits are violated
• acquires, displays, and prints diagnostic-quality 12-lead reports
ECG traces for multiple leads can be displayed, however, ECG monitoring is
always performed on two leads. Lead faults are identified by a message on the
screen. If automatic lead switching is enabled, the system automatically switches
to another appropriate lead to continue monitoring in the event of a lead fault.
ECG Setup
The ECG waveform area displays the CHECK SETUP key and sounds an alarm
when the monitor is powered ON, following a monitor reset, and after an ECG
module is inserted. Touch the ECG key to dismiss the CHECK SETUP key and
silence the alarm. Verify that the system configuration (for example, alarm limits,
lead selection, etc.) is appropriate before you begin, or resume, monitoring.
WARNING:
• Following a lead switch and until the patient’s rate and
morphology are learned, some ECG alarms are not active.
Alarms for ventricular fibrillation and asystole continue to
be active. However, ECG alarms for high rate, low rate, run,
couplet, abnormal per minute, and tachycardia are not.
!
• Monitor input circuits are protected for electrosurgical
equipment and defibrillator use.
• Cardiac pacemakers or other electrical stimulators do not affect
and are not affected by operation of this unit.
• You can define your own default settings for such
characteristics as alarm limits and display configuration. Refer
to Module Configuration Manager on page 7-5 for further
information.
!
• When the Check Setup feature is disabled, the CHECK SETUP
key will not display and its associated alarm tone will not sound.
Contact your system administrator to enable this feature.
WARNING:
• Signals resulting from devices such as Automatic
Implantable Cardiac Defibrillators (AICD) may momentarily
blank the ECG trace rather than display an out-of-range
signal. In such cases, it may not be apparent that the AICD
has fired and the condition of the patient should be
checked. In all instances of AICD firing, the monitor will
redisplay the ECG waveform within 5-seconds.
