Correcting Common Problems
Pacemaker
interference
Intermittent connections or
metal-to-metal sparking
1) Check all connections to the
generator.
2) It may be necessary to re-
program the pacemaker.
Current traveling from active to
return electrode during
monopolar electrosurgery is
passing too close to pacemaker
1) Use bipolar instruments, if
possible. If you must use a
monopolar instrument, place
the patient return electrode as
close as possible to the surgical
site.
2) Make sure the current path
from the surgical site to the
patient return electrode does
not pass through the vicinity of
the heart or the site where the
pacemaker is implanted.
3) Always monitor patients with
pacemakers during surgery and
keep a defibrillator available.
4) Consult the pacemaker
manufacturer or hospital.
5) Contact the hospital’s
Cardiology Department for
further information when use
of electrosurgical appliances is
planned on patients with
cardiac pacemakers.
