Electromagnetic interference will not damage your pacemaker but may temporarily interfere with its settings whilst you are in contact with it. Most mechanical and electrical devices that you use in your normal daily activities will not affect your pacemaker. Household equipment such as ordinary radios, fridges, cookers, remote controls, televisions, electric razors, computers and microwaves etc. will not affect your pacemaker as long as they are in good working order.
Magnets: Do not carry magnets or place a magnet over your chest. Avoid carrying stereo or hi-fi speakers as they contain strong magnets that can interfere with your pacemaker.
Shop doorway security systems: It is advised that you walk through shop doorway security systems at a normal pace and not to wait around in this area.
Medical equipment / other hospital treatments: Most equipment used by your hospital or GP surgery will not cause any problems to your pacemaker. However it is advised that you let medical and dental staff know that you have a pacemaker. Please take your ID card with you whenever you go to hospital.
It is safe for you to have X-rays, CT scans and mammograms.
You should however avoid magnetic resonance imaging (MRI) machines unless you are told you device is MRI compatible. Some electrical nerve and muscle stimulators (TENS units) may cause interference with pacemakers but this depends on where they are being applied, and, if any of these treatments are suggested to you then your pacemaker clinic should be contacted for advice.
Travel: You can safely travel abroad with your pacemaker, but you are advised to show the security staff your identification card. Walk through the metal detector archway if asked to do so, but the metal casing of the device may set off the airport security alarm. The detector will not cause any harm to your pacemaker provided you walk briskly through the arch.
Arc welding: Generally, this should be avoided.
Mobile phones: Some studies have shown that some mobile phones can affect the pacemaker if held within 10 centimetres of the device. It is therefore recommended that you do not keep a mobile phone in a coat or shirt pocket over the pacemaker. Keep the handset more than 10 centimetres away from the pacemaker; ideally hold the phone over the ear on the opposite side to the device.
