Electromagnetic interference in everyday life

(cell phone/smartphones, smartwatches, garden equipment, microwave, induction stove, airport, shops, electric cars, …)

Caution should be taken for:

• You can use a cell phone or smartphone but should try to keep a distance of 15-30 cm between the device and the phone. Please note that newer smartphones can bear a strong magnet (e.g. iphone 12+) which can deactivate some ICD functions when held directly above the device.
• An induction stove uses a magnet field to generate the heat. You can use an induction stove but should keep a distance of 50 cm between the stove and your device while the stove is on.
• At the airport, the security checks can use electromagnetic fields to scan the passengers. You should inform the security guards that you have an implanted cardiac device. They will probably guide you to an alternative security check and perform the check manually. It is recommended to have your implant ID with you as a certificate.

 

Can be used without further restrictions:

• Smartwatches
• A microwave
• Gardening equipment like electric secateurs or mowers can be used without further restrictions. Please assure that all equipment is adequately grounded.

 

Many manufacturers of cardiac devices provide more detailed overviews and instructions for patients:

• Medtronic
• Biotronik
• Abbott
• Boston Scientific

FREQUENTLY ASKED QUESTIONS

What is electromagnetic interference?

Electromagnetic interference (EMI) is disruption in the functioning of a cardiac device caused by nearby electronic devices.

Can everyday devices interfere with cardiac devices?

Some devices with strong electromagnetic fields, like MRI machines or industrial equipment, can interfere with cardiac devices. Most household electronics are safe.

Is it safe to use a microwave with a pacemaker or ICD?

Yes, modern pacemakers and ICDs are shielded from interference caused by microwaves.

Can cell phones affect cardiac devices?

Cell phones are generally safe, but it is recommended to keep them at least 6 inches away from the device.

What precautions should be taken with metal detectors?

While passing through metal detectors is generally safe, prolonged exposure or handheld scanners near the chest should be avoided.

Can headphones or earbuds interfere with cardiac devices?

Headphones with magnets should not be placed near the chest or device. It’s safe to use them with appropriate distance.

Are electric vehicles safe for cardiac device users?

Electric vehicles are generally safe, but users should consult their cardiologist if they feel any device-related discomfort.
