2.7 Warnings, precautions, and guidance related to
electromagnetic interference (EMI) for cardiac device
patients
Many cardiac device patients resume their normal daily activities after full recovery from
surgery. However, there may be certain situations that patients need to avoid. Because a
cardiac device is designed to sense the electrical activity of the heart, the device may sense
a strong electromagnetic energy field outside of the body and deliver a therapy that is not
needed or withhold a therapy that is needed. The following sections provide important
information to share with patients about electrical equipment or environments that may
cause interference with their implanted cardiac device.
For additional guidance about EMI, customers can contact the following resources:
●
Customers in the United States can contact either of the following telephone numbers:
for pacemakers, contact Medtronic Technical Services at +1 800 505 4636; for ICDs,
contact Medtronic Technical Services at +1 800 723 4636. You may also submit
questions to tshelp@Medtronic.com or your Medtronic representative.
●
Customers outside of the United States can contact a Medtronic representative.
General EMI guidelines for patients – Patients should observe the following general
guidelines regarding EMI:
●
Area restrictions – Before entering an area where signs are posted prohibiting persons
with an implanted cardiac device, such as a pacemaker or ICD, consult with your doctor.
●
Symptoms of EMI – If you become dizzy or feel rapid or irregular heartbeats while using
an electrical item, release whatever you are touching or move away from the item. The
cardiac device should immediately return to normal operation. If symptoms do not
improve when you move away from the item, consult with your doctor. If you have an
ICD and you receive a therapy shock while using an electrical item, release the item or
move away from it, then consult with your doctor.
●
Proper grounding of electrical items – To avoid interference from electrical current that
may leak from improperly grounded electrical items and pass through the body, observe
the following precautions:
– Make sure that all electrical items are properly wired and grounded.
– Make sure that electrical supply lines for swimming pools and hot tubs are properly
installed and grounded according to local and national electrical code requirements.
