rate drops below the set pacing rate. The pacing rate
should be set at a level sufficient for adequate
cardiac output.
4. Check the threshold periodically.
Asynchronous Pacing
If ECG electrodes are not available or there is some
circumstance that prevents or interferes with the surface
ECG, it may be necessary to operate the pacemaker
asynchronously.
Perform asynchronous pacing only in emergency
situations when there are no other alternatives.
To pace asynchronously:
1. Press the Async Pacing On/Off Softkey.
The display shows the ASYNC PACE message to
indicate that asynchronous pacing has been
activated. The annotation “ASYNC PACE” is printed
on the stripchart when activated by the RECORDER
button. This annotation is also printed on the
corresponding summary report.
2. To return to demand pacing, press the Async Pacing
On/off softkey again and the display returns to
PACE.
Pace stimuli is also delivered asynchronously whenever
there is an ECG LEAD OFF condition. Be aware that
there is no ECG activity on the display when pacing by
this method; you must use other means of determining
capture such as checking the patient’s pulse. When
pacing asynchronously with an ECG LEAD OFF
condition, set the rate and mA at the known capture level
or high enough (100mA) to presume capture.
Pediatric Pacing
Noninvasive pacing of pediatric patients is done in an
identical manner to adult pacing. Smaller size pediatric
MFE Pads are available for patients weighing less than
33 lbs/15 kg. Continuous pacing of neonates can cause
skin burns. If it is necessary to pace for more than 30
minutes, periodic inspection of the underlying skin is
strongly advised. Carefully follow all instructions
provided on electrode package.
Troubleshooting
