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
If your E Series unit does not function as expected, see 
the troubleshooting section “Pacer (Pacer version only)”
