Cautionary Notes

After stimulation, the pacemaker function and pacing threshold must
be checked. For home use, the electrode positioning and current
strength settings must be such that the nerve stimulation does not
interfere with pacemaker functioning.
Magnetic Resonance Imaging (MRI)
This diagnostic procedure is contraindicated for pacemaker patients,
because a variety of complications may result, e.g., repositioning;
pulse inhibition; asynchronous and/or triggered pacing—depending on
the pacing mode and the interference pattern of the implanted
pacemaker—; damage to the circuitry; tissue damage in the vicinity of
the pacemaker and/or tip electrode; and lead dislocation.
If this procedure cannot be avoided, the patient and his/her peripheral
pulse must be constantly monitored. After an MRI, the pacemaker
function and pacing threshold must be checked and monitored for a
sufficient period of time.
Lithotripsy
This treatment is contraindicated for pacemaker patients because
electrical and/or mechanical interference with the pacemaker is
possible. If it must be used, the selected site for electrical and
mechanical stress should be as far away as possible from the
pacemaker. The patient's peripheral pulse should be continuously
monitored throughout the treatment. After the procedure, the
pacemaker function must be checked and monitored for a sufficient
period of time.
