Environmental and Medical Therapy Hazards
Avoid electromagnetic interference (EMI). Advise patients to avoid sources of EMI because EMI may
cause the pulse generator to deliver inappropriate therapy or inhibit appropriate therapy.
Moving away from the source of the EMI or turning off the source usually allows the pulse generator
to return to normal operation.
Examples of potential EMI sources are:
Electrical power sources, arc welding or resistance welding equipment, and robotic jacks
High voltage power distribution lines
Electrical smelting furnaces
Large RF transmitters such as radar
Radio transmitters, including those used to control toys
Electronic s urveillance (antitheft) devices
An alternator on a car that is running
Medical treatments and diagnostic tests in which an electrical current is passed through the body,
such as TENS, electrocautery, electrolysis/thermolysis, electrodiagnostic testing, electromyography,
or nerve conduction studies
Any externally applied device that uses an automatic lead detection alarm system (e.g., an EKG
machine)
Wireless ECG. W ireless ECG is susceptible to RF interference, and may have an intermittent or lost
signal. If interference is present, especially during diagnostic testing, consider using a surface ECG
instead.
