Dielectric heaters used in industry to heat plastic and dry glue in furniture manufacturing
●
Electric arc and resistance welding equipment
●
Broadcasting antennas of AM, FM, shortwave radio, and TV stations
●
Microwave transmitters. Note that microwave ovens are unlikely to affect cardiac
devices.
●
Power plants, large generators, and transmission lines. Note that lower voltage
distribution lines for homes and businesses are unlikely to affect cardiac devices.
Radio transmitters – Determining a safe distance between the antenna of a radio
transmitter and a cardiac device depends on many factors such as transmitter power,
frequency, and the antenna type. If the transmitter power is high or if the antenna cannot be
directed away from a cardiac device, you may need to stay farther away from the antenna.
Refer to the following guidelines for different types of radio transmitters:
●
Two-way radio transmitter (less than 3 W) – Keep a cardiac device at least 15 cm (6 in)
away from the antenna.
●
Portable transmitter (3 to 15 W) – Keep a cardiac device at least 30 cm (12 in) away
from the antenna.
●
Commercial and government vehicle-mounted transmitters (15 to 30 W) – Keep a
cardiac device at least 60 cm (24 in) away from the antenna.
●
Other transmitters (125 to 250 W) – Keep a cardiac device at least 2.75 m (9 ft) away
from the antenna.
For transmission power levels higher than 250 W, contact a Medtronic representative
for more information.
Security systems – When passing through security systems, follow these precautions:
●
Electronic antitheft systems, such as in a store or library, and point-of-entry control
systems, such as gates or readers that include radio frequency identification
equipment – These systems should not affect a cardiac device, but as a precaution, do
not linger near or lean against such systems. Simply walk through these systems at a
normal pace. If you are near an electronic antitheft or entry control system and
experience symptoms, promptly move away from the equipment. After you move away
from the equipment, the cardiac device resumes its previous state of operation.
●
Airport, courthouse, and jail security systems – Given the short duration of security
screening, it is unlikely that metal detectors (walk-through archways and hand-held
wands) and full body imaging scanners (also called millimeter wave scanners and
three-dimensional imaging scanners) in airports, courthouses, and jails will affect a
cardiac device. When encountering these security systems, follow these guidelines:
– Always carry your cardiac device ID card. If a cardiac device sets off a metal detector
or security system, show your ID card to the security operator.
